TDA8295
Digital global standard low IF demodulator for analog TV and FM radio
9.3.20 GPIOs
In the TDA8295, three general purpose input/outputs are implemented.

Description
7 to 4 GP1_CF[3:0]
R/W
It determines how the general purpose pin GPIO1 is
configured.
0000
The GPIO1 pin is in Input mode. The input value is
stored in GP1_VAL.
0001*
The GPIO1 pin is in Open-drain mode. The output
value is determined by GP1_VAL.
0011
The GPIO1 pin is in Output mode. The PLL output
clock divided by two is delivered.
0100
to
1011
The GPIO1 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 like described in
3 to 0 GP0_CF[3:0]
R/W
It determines how the general purpose pin GPIO0 is
configured.
0000
The GPIO0 pin is in Input mode. The input value is
stored in GP0_VAL.
0001*
The GPIO0 pin is in Open-drain mode. The output
value is determined by GP0_VAL.
0011
The GPIO0 pin is in Output mode. The PLL output
clock divided by two is delivered.
0100
to
1011
The GPIO0 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.

When I2CSW_EN = 1, GPIO1 and GPIO2 are
configured as an I2C-bus feed-through independently of
the GP1_CF and GP2_CF value. When
I2CSW_ON = 0, the feed-through switch is open, and
GPIO1 and GPIO2 are in 3-state. When the switch is
closed (I2CSW_ON = 1), the I2C-bus clock and data
signals (SCL and SDA) are available on the GPIO1 and
GPIO2 pins.
