6.26.10 Clamp and Linear Mapping
BIT1612 有輸出範圍線性對映運算單元，並附帶箝位功能，其運算單元位於Gamma Correction的後
級，可以對Gamma Correction後的RGB圖像再進行調整，其相關設定Registers請參考 Table 6-38。 當只
需要輸出箝位功能時，只要將R_CLAMP_EN設為 1，並由輸出最大值 MAX回推
R_OUT_DACMAP_SPACE值，最小值MIN回推R_OUT_DACMAP_LB值，即可使RGB輸出值介於MAX到
MIN之間。公式如下：
MAX = 256 + R_OUT_DACMAP_SPACE (V)
MIN = R_OUT_DACMAP_LB
(V)
當輸出需要線性對映功能時，則可以設定R_DACMAP_EN為 1，且將R_CLAMP_EN設為 0，其輸出
範圍與上面公式相同，比較輸入與輸出線性關係，在R_CLAMP_EN為 1 時，其輸入輸出轉換曲線斜率為 1
，而R_DACMAP_EN = 1 時，則可以透過R_OUT_DACMAP_LB與R_OUT_DACMAP_SPACE調整，其差
別可以參考 Figure 6-24 及 Figure 6-25。

OSD的架構如 Figure 6-39 所示：
使用 R_Wx_INDEXS 和 R_Wx_INDEXE 來指出要由 Display RAM 的第幾個 ”WORD” 開始取 Data (
同時取用 0x5xx 和 0x4xx 相對應的 Data)，其中 0x5xx[6] 用來控制 ”Background Fade Enable” (須搭配
R_Wx_FADE)、0x5xx[5]用來控制 “Foreground Blink Enable” (須搭配 R_Wx_CYCLE)、0x5xx[3:0]用來選
擇 16 個 Palette 中的某一個和 { 0x5xx[4], 0x4xx[6:0] } 用來控制要選取那一個 Font (0x00~0x7F：定義為
“Fixed Font” (128 個) , 0x80~0xAF：定義為 “User Font” (48 個)，和 0xB0~0xBF：定義為 “Color Font” (16
個) )。
另外在Palette RAM部份是以 4 個連續位址當一個屬性，位址 “0” 的 “bit5” 用來控制 “Fringe Enable”
、位址 “0” 的 “bit4” 用來控制 “Foreground Transparent Enable” (等於 1 時，完全透過去)、位址 ”0” 的
”bit3” 用來控制 ”Background Transparent Enable” (等於 1 時，完全透過去)、位址 ”0” 的 ”bit2~0” 及位
址 ”1” 的 ”bit5~0” 用來控制 ”Foreground Color”；位址 ”2” 的 ”bit4” 用來控制 ”Foreground Fade
Enable” (須搭配R_Wx_FADE)；位址 ”2” 的 ”bit3” 用來控制 ”Background Blink Enable” (須搭配
R_Wx_CYCLE) 和位址 ”2” 的 ”bit2~0” 及位址 ”3” 的 ”bit5~0” 用來控制”Background Color”，可參考
Figure 6-40 及 Figure 6-41。
而在 ”User Font” 和 ”Color Font” 部份是採用共用RAM的方式來設計，分別有 48 及 16 個Font。在
”User Font” 的部份則是以 32 個RAM位址的Data來組合成一個Font (可參考”Figure 6-42”)；在 ”Color
Font” 的部份則是以 96 個RAM位址的Data來組合成一個Font (可參考 Figure 6-43)。

6.37 Auto Detection
BIT1612 提供七種輸入訊號偵測機制，分別為 PCLK Base SYNC Detection、XCLK Base HSYNC Detection
、Mode Change Detection、Mode Type Detection、Even/Odd Type Detection、Data Enable Signal Detection
和 No Signal Detection。
1.
PCLK Base SYNC Detection:
以 PCLK 偵測 External HSYNC、External VSYNC Low Pulse Width 及 Total SYNC Width，其主要作為
SYNC 極性判別及模式的偵測，此偵測機制 Power On 時就會自動啟動且無法由 MCU 去終止或啟動，
其操作步驟如下：
(讀取偵測 SYNC 資料：)
Register (0x160[7:0]):
HSYNC Low Pulse (in PCLK)。
Register (0x164[7:4], 0x161[7:0]): HSYNC Total Width (in PCLK)。
Register (0x162[7:0]):
VSYNC Low Pulse (in HSYNC)。
Register (0x164[2:0], 0x163[7:0]): VSYNC Total Width (in HSYNC)。
2.
XCLK Base HSYNC Detection:
以 XCLK 偵測 External HSYNC，其主要作為模式的判別。此偵測機制會以 XCLK 為基準計算 Input
HSYNC Low Level Width 和 HSYNC High Level Width，其操作步驟如下：
(讀取偵測 HSYNC 資料：)
Register (0x167[7:4], 0x165[7:0]): HSYNC High Level Width (in XCLK)。
Register (0x167[3:0], 0x166[7:0]): HSYNC Low Level Width (in XCLK)。
3.
Mode Change Detection:
偵測 VSYNC 變化量，如果 VSYNC 變化量大於 8 條 HSYNCs，將會經由 Interrupt 機制回應給 MCU 得
知，其操作步驟如下：
Set Interrupt Enable (Register: 0x004[2])。
如果 VSYNC 變化量大於 8，將會由 INT Pin 發出 Interrupt，亦可藉由輪詢的方式讀取 Interrupt Flag
(Register: 0x002[2]) 而得知。
4.
Mode Type Detection:
73
BIT1612
10-Bit Digital Video Decoder with OSD and T-CON
自動辦別 NTSC/PAL Mode 並可由 Register (0x16A[1]) 直接讀出其狀態。
5.
EVEN/ODD Type Detection:
自動判別 VSYNC 是否有 EVEN/ODD 相關變化，並可由 Register (0x16A[2]) 直接讀出其狀態。
6.
Data Enable Signal Detection:
自動偵測 Data Enable Signal Information 以供系統作為設定 Input Windows 的參考。
7.
No Signal Detection:
自動判別 HSYNC 是否有 Toggle，如果在 2047 XCLKs 內沒有變化將由 Interrupt (0x002[1:0]) 回應或
可由 Register (0x16A[3]) 直接讀出其狀態。

7 User Interface
BIT1612 提供二種 Interface Mode (Slave Mode 和 Script Master Mode)，使其能應用在不同的環境中。
7.1 Options Pins
BIT1612 使用 6 根外部 Pins 來做 Mode 的選擇。主要可以分為 Master 與 Slave Mode。Slave Mode 下，外
部的 MCU 可以經由 Pin OP1、OP0 控制 BIT1612，並視需要選擇 Two-Wire Serial Interface (TWSI) Protocol 或
是 Bitek Bus Protocol。Master Mode 則是運用 BIT1612 內建 CPU 搭配外部程式記憶體完成系統設計。在 Master
Mode 下 Script MCU 則只需要搭配 24 系列的 Serial EEPROM，並利用 Bitek 自行定義的指令集，即可完成 BIT1612
的相關控制。
Script MCU支援三種工作模式，分別是Single 24C16、Single 24C32 與Dual 24C16。Single 24C16 Mode可
以支援單顆 24C16 以下的EEPROM；24C32 Mode可以支援單顆 24C32 系列的EEPROM (24C32/24C64)；Dual
24C16 Mode可以運用 { OP2, OP3 } 做為第二組TWSI介面，擴充程式記憶體，最多可支援兩顆 24C16，定義及

Start and Interrupt
BIT1612 內建Script Control Function提供Interrupt Process機制，用以處理BIT1612 所產生的Interrupt
(0x002[7:0])，並且支援自動Re-ACK機制，以減少程式碼的複雜度。相關的程式起始位置請參考 Table 7-6

Serial EEPROM and ROM Space Mapping
BIT1612 在硬體上可支援 24C16 及 24C32 兩種Serial EEPROM的通訊協定，指令集支援最高 2K的
定址空間。使用小於 2KB程式記憶體時可以完全對映，但使用超過 2KB時，則需利用Bank Selection的方
式擴增定址空間，運用R_EEPROM_BANK_SEL可以支援到 64KB的ROM Size (24C512)，如 Figure 7-5
所示。
84
BIT1612
10-Bit Digital Video Decoder with OSD and T-CON
Figure 7-5 BIT1612 Script Controller Addressing Space
有些應用上希望使用超過 2KB的程式記憶體，除了使用 24C32 外，BIT1612 提供兩組TWSI的方式來
進行程式記憶體空間的擴充，如 Figure 7-4。無論使用單 24C32 或是雙 24C16 的方式，在做跨Bank的動
作時，一定要先設定R_EEPROM_BANK_SEL到正確的BANK。以 Figure 7-4 的情況為例：
……
MOV R_EEPROM_BANK_SEL, 001h
MOV R_REG_ADDR_L, 0A0h
MOV R_REG_ADDR_H, 003h
TABLE
MOV B, A
DEC
……
; ROM 1, BANK0
; A<= ROM2[0A0h], BANK1
; ROM1, BANK0
而在定址空間邊界上，則不能讓單一指令跨 BANK，如 MOV S, #NUM 為 4-Byte 的指令，則 MOV S,
#NUM 不能存放於 0x7FD、0x7FE、0x7FF，但可以存放在 0x7FC ~ 0x7FF。
0x7FC MOV S, NUM (OP Code)
0x7FD NUM 1
0x7FE NUM 2
0x7FF NUM 3
7.2.5
Serial EEPROM Write Protection and Power Monitor
BIT1612 新增Power Monitor 與Dynamic Write Protection功能，避免EEPROM在惡劣環境下產生非
預期的誤動作。Dynamic Write Protection功能可以參考 Figure 7-2，將BIT1612 的OP2 接至 24C16 的WP
Pin，並將R_WP_EN設為 1 即可。Power Monitor功能則是會監控電壓是否正常，若不正常將停止對Serial
EEPROM讀寫，並對Script MCU Reset，要使用此功能只要將R_PG_EN設為 1，經過電壓比較器輸出的
訊號接至BIT1612 的GIN7 即可。
7.2.6
Watch Dog Timer
BIT1612 有一 Watch Dog Timer (WDT)，R_WDT_SEL 可以選擇 Timer 的 Interval，當超過此 Interval
85
BIT1612
10-Bit Digital Video Decoder with OSD and T-CON
沒有對 R_WDT_CLEAR 執行寫入 1、寫入 0 的動作，Script MCU 會自動 Reset，透過 R_WDT_OV 可以
得知本次 Reset 是起因於正常開機還是 WDT Overflow 所導致。
7.2.7
Second TWSI for Multi-Processor Communication
BIT1612 預留OP2 and OP3 為Multi-Processor Communication Port，其Protocol與TWSI相容，透過
設定R_TWSI_SEC可以開啟此功能，其示意圖如 Figure 7-3。其工作原理是在此BUS上的動作符合預設的
條件時，就會產生中斷，此時中斷服務程式就可以執行Multi-Processor Communication的程式。
設定 R_TWSI_DET_MODE 可以決定 TWSI 何種動作會觸動 Interrupt[3]；R_TWSI_SEC_SLAVE[1:0]
決定 BIT1612 在 TWSI 上的 Device Address，R_TWSI_DET_IN[7:0]及 R_TWSI_DET_OUT[7:0]則是透過
此 BUS 讀寫的資料，R_TWSI_DET_VALUE 配合 R_TWSI_DET_MODE 可以在特定的 Register Address
下產生中斷。
7.2.8
TWSI Write/Read
BIT1612 可以運用 MOV @IADDR, A 和 MOV A, @IADDR 指令，與 R_TWSI_SLAVE 方便地存取位
於 { OP1, OP0 } 上的元件內部資料，與 Serial EEPROM 相同，透過最省成本的分時多工方式完成周邊控
制，要注意 TWSI 由於是分享給不同的 Device，所以不允許此 TWSI 上同時有第二個 Device Address 是
1010XXX 的元件出現。
7.2.9
SPI Interface
BIT1612 為了支援 SPI Interface 的 LCD Panel，附加了符合多種規格的 SPI Interface 的功能，透過
R_SPI_CTRL 及 MOV S, #NUM 指令可輕易地完成 LCD Panel 設定功能。SPI 信號可由 R_SPI1_EN 及
R_SPI2_EN 選擇由 BOUT Port 或是 SRGB_D Port 輸出。
7.2.10
Debug Mode
為了方便在韌體工程師設計 Master Mode 的程序，將 R_MCU_DEBUG 設為 1，切換 Master 與 Slave
時將不會 Reset，因此可以運用 Master 執行到一 HALT 點後，再切換至 Slave Mode 讀回 BIT1612 內部狀
態的技巧進行 Debug。若應用於 Slave Mode 則必須將 R_MCU_DEBUG 設為 0。
86
BIT1612
10-Bit Digital Video Decoder with OSD and T-CON
7.3 Slave Mode
BIT1612 提供 BiTEKbus 或 Two-Wire Serial Interface (TWSI) 兩種 Protocol 來存取 Register Sets，並由 OP4
Pin 來決定所選用的 Protocol。當 OP4 為 1，選用 BiTEKbus Protocol；當 OP4 為 0，則選用 TWSI Protocol。
7.3.1

BIT1612 可由外部 Pins (OP3 and OP2) 來決定 Slave Address，相關的 Slave Address 請參考下表。

7.3.2.1 TWSI Protocol Device Address
BIT1612 TWSI Protocol 須在送出 Start Bit 之後送出 8 Bits Device Address (Slave Address)，並
可由外部 PIN (OP3 and OP2)決定其 Device Address 的 Bit6 and Bit5 位址。相關設定請參考下表。

10 Soldering Information
10.1 Reflow Soldering
The choice of heating method may be influenced by plastic QFP package). If infrared or vapor phase
heating is used and the package is not absolutely dry (less than 0.1% moisture content by weight),
vaporization of the small amount of moisture in them can cause cracking of the plastic body. Preheating is
necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C.
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be
applied to the printed-circuit board by screen printing, stenciling or pressure-syringe dispensing before
package placement. Several methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100
and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 to 270 °C depending on solder paste material. The
top-surface temperature of the packages should preferable be kept below 245 °C for thick/large packages
(packages with a thickness ≧ 2.5 mm or with a volume ≧ 350 mm3 so called thick/large packages). The
top-surface temperature of the packages should preferable be kept below 260 °C for thin/small packages
(packages with a thickness < 2.5 mm and a volume < 350 mm3 so called thin/small packages).

10.2 Wave Soldering
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or
printed-circuit boards with a high component density, as solder bridging and non-wetting can present major
problems.
10.3 Manual Soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less)
soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C.
When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
