6. Functional Description
6.1 General Description
The F75121 provides VIDIN, VIDOUT function. It can latch the VIDIN from CPU side, and output VIDOUT to
PWM. The VIDOUT value can be programmed by the interface GPIO Serial Bus serial interface.
Dedicate GPIO functions. That includes two set watchdog timer. The watchdog timer timeout unit is set to second
and range is 0 to 31 seconds. When the timeout has occurred, that will generate a status bit to indicate it and write
one will be clear.
All GPIO can be programmed to logic one or zero or high pulse or low pulse.

V0.24P
Providing CPU on board detection (SLOTOCC#). The detection circuit is powered by battery. That is latch circuit
is powered by VBAT. The de-bounce circuit should be added to avoid low power noise. The de-bounce circuit is
generated by internal low frequency clock with 32K Hz to filter out the low-to-high or high-to-low glitch.
6.2 Access Interface
The F75121 provides one serial access interface, Serial Bus, to read/write internal registers. The address of Serial
Bus is configurable by using power-on trapping of standby power VBS3V. The pin 11 (GPIO11/I2C _ADDR) is
multi-function pin. During the VSB 3V power-on, this pin serves as input detection of logic high or logic low. This pin is
default pull-down resistor with 100K ohms mapping the Serial Bus address 0x9C (1001_1100). Another Serial Bus
address 0x6E (0110_1110) is set when external pull-up resistor with 10K ohms is connected in this pin.

6.4 VID Function
Please refer to control registers.
6.5 GPIO Function
The GPIO functions in the F75121 include general GPIO with programming Input and output. The output function also can be
programmed high level or low level or high pulse or low pulse.
CPU Voltage ID (VID) function
The F75121 provides a voltage adjustment in the CPU with VID control. In general, the VIDIN is connected to CPU
VID<4:0>(VRM9.X) or VID<5:0>(VRM10.0) and VIDOUT is connected to PWM Vcore VID. In the first power-on, the VIDIN is
bypassed to VIDOUT.
