(a) When (EXCK1, EXCK0) = (0, 0) ......External synchronous 1 (External clock display) … Fosc = 20 to 70 MHz Input from the TCK pin a constant-period continuous external clock that synchronizes with the horizontal synchronous signal. And input from HOR pin a constant period continuous horizontal synchronous signal. Never stop inputting the clock while displaying. Do not have to set a display frequency because the clock just as it is entered from outside is used as the display clock. (b) When (EXCK1, EXCK0) = (0, 1) ......Internal synchronous… Fosc = 20 to 90 MHz Clock input from the TCK pin is unnecessary. The multiply clock of the internally generated horizontal synchronous signal is used as the display clock. The display frequency is set by setting the multiply value of the horizontal synchronous frequency (of the display frequency) in DIV10 to DIV0 (address 12016). Also, set the display frequency range. (See the next page.) Display frequency is calculated using the below expression. (c) When (EXCK1, EXCK0) = (1, 0) ......… Setting disabled (d) When (EXCK1, EXCK0) = (1, 1) ......External synchronous 2 (Internal oscillation clock display) … Fosc = 20 to 90 MHz Input from the TCK pin a constant-period continuous external clock that synchronizes with the horizontal synchronous signal. And input from HOR pin a constant-period continuous horizontal synchronous signal. Never stop inputting the clock while displaying. An internal clock which is in sync with the external input clock is used as the display clock. Because the display frequency equals the external clock frequency, set N1 (division value) that satisfies the below expressions to DIV10 to DIV0 (address 12016) for make the display frequency is equal to the external clock frequency. N1 = external clock frequency / horizontal synchronous frequency 10 N1 = Σ n=0 2nDIVn Also, set the display frequency range. (See the next page.) Display frequency = Horizontal synchronous frequency x Multiply value Horizontal synchronous signal 1H External clock Number of clock (N1) Fig. 4 Example of external clock input 17 MITSUBISHI MICROCOMPUTERS M35071-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS (2) To set display frequency range Whenever setting display frequency (when EXCK1 = "0", EXCK0 = "1", or EXCK1 = "1", EXCK0 = "1"), always set the display frequency range in accordance with the display frequency. This range is set from DIVS0, DIVS1 (address 12016), RSEL0 address 12116) and RSEL1 (address 12216). Frequency ranges are given here below. RSEL1 RSEL0 1 1 DIVS1 0 DIVS0 Display frequency range (MHz) 0 87.0 to 90.0 1 0 0 0 67.0 to 87.0 0 1 0 0 54.0 to 67.0 1 0 0 1 47.0 to 54.0 0 0 0 0 40.0 to 47.0 1 0 1 0 34.0 to 40.0 0 0 0 1 30.0 to 34.0 0 1 1 0 26.0 to 30.0 1 0 1 1 23.0 to 26.0 0 0 1 0 20.0 to 23.0 (3) Notes on setting display frequency To change external clock (display) frequency or horizontal synchronization frequency, always use the following procedures. To set EXCK1 = "0", EXCK0 = "1" (a) Turn the display OFF. … DSPON (address 12816) = "0" (b) Set the display frequency. … Set from DIV10 to DIV0, DIVS0, DIVS1 (address 12016), RSEL0 (address 12116) and RSEL1 (address 12216). (c) Wait 20 ms while the horizontal synchronization signal is being input. (d) Turn the display ON. … DSPON (address 12816) = "1" To set EXCK1 = "1", EXCK0 = "1" (a) Turn the display OFF. … DSPON (address 12816) = "0" (b) Set the display frequency. … Set from DIV10 to DIV0, DIVS0, DIVS1 (address 12016), RSEL0 (address 12116) and RSEL1 (address 12216). (c) Wait 20 ms while the horizontal synchronization signal and external clock are being input. (d) Turn the display ON. … DSPON (address 12816) = "1" 18 MITSUBISHI MICROCOMPUTERS M35071-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS DISPLAY FORM 1 Matrix-outline size : Blanking the background 12 × 18 dot.

In communications, this IC functions as a slave reception device. The IC is synchronized with the serial clock (SCL) sent from the master device and receives the data (SDA). Communications are controlled from the start/stop states. Also, always input the control byte after attaining the start state. The below chart shows the start/stop state and control byte configuration. SCL SDA Start state Data receive Data modify enable Stop state Fig. 12 Start state / Stop state Control byte: 7C16(Fixed) Slave address 0 1 1 1 1 R/W 1 0 0 (0: Written) Fig. 13 Control byte configuration 25 MITSUBISHI MICROCOMPUTERS M35071-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS (2) Data input (Sequence) (a) Addresses are consists of 16 bits. (b) Data is consists of 16 bits. (c) Addresses and data are communicated in 8-bit units. Input the lower 8 bits before the upper 8 bits. Make input from the MSB side. (d) After the start state has been attained and the control byte (7CH) received, the next 16 bits (2 bytes) are for inputting the address. Addresses are increased in increments for every 16 bits (2 bytes) of data input thereafter. As a result, it is not necessary to input the address from the second data. Note: During external synchronous, stop the external clock input from the TCK pin while inputting data.
