Digital global standard low IF demodulator for analog TV and FM radio
3 to 0
GP2_CF[3:0] R/W
It determines how the general purpose pin GPIO2 is
configured.
0000
The GPIO2 pin is in Input mode. The input value is
stored in GP2_VAL.
0001*
The GPIO2 pin is in Open-drain mode. The output
value is determined by GP2_VAL.
0011
The GPIO2 pin is in Output mode. The PLL output
clock divided by two is delivered.
0100
to
1011
The GPIO2 pin is in Output mode. HVPLL signals are
delivered. The output is a one bit signal of
HVPLL_BUS[7:0] according to Table 64.
XXXX
Don’t care if I2CSW_EN = 1. Then the pad is
configured as I2C-bus feed-through.

GP2_VAL
R/W
1*
GP2_VAL controls the value of the pin GPIO2 when
GP2_CF[3:0] = 0001. When GP2_CF[3:0] = 0000,
GPIO2 is an input pin which value can be read
through the I2C-bus stored in GP2_VAL.

GP1_VAL
R/W
1*
GP1_VAL controls the value of the pin GPIO1 when
GP1_CF[3:0] = 0001. When GP1_CF[3:0] = 0000,
GPIO1 is an input pin which value can be read
through the I2C-bus stored in GP1_VAL.
0
GP0_VAL
R/W
1*
GP0_VAL controls the value of the pin GPIO0 when
GP0_CF[3:0] = 0001. When GP0_CF[3:0] = 0000,
GPIO0 is an input pin which value can be read
through the I2C-bus stored in GP0_VAL.
