Description
It determines how the general purpose pin GPIO1 is
configured.
It determines how the general purpose pin GPIO0 is
configured.
Description
When I2CSW_EN = 1, GPIO1 and GPIO2 are
configured as an I
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 I
signals (SCL and SDA) are available on the GPIO1 and
GPIO2 pins.
not used
The GPIO1 pin is in Input mode. The input value is
stored in GP1_VAL.
The GPIO1 pin is in Open-drain mode. The output
value is determined by GP1_VAL.
The GPIO1 pin is in Output mode. The PLL output
clock divided by two is delivered.
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
Don’t care if I2CSW_EN = 1. Then the pad is
configured as I
Table
The GPIO0 pin is in Input mode. The input value is
stored in GP0_VAL.
The GPIO0 pin is in Open-drain mode. The output
value is determined by GP0_VAL.
The GPIO0 pin is in Output mode. The PLL output
clock divided by two is delivered.
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
