Description
It determines how the general purpose pin GPIO2 is
configured.
Description
With CLK_INV_GPx, the output clock polarity can be
changed. This is only useful when
GPx_CF[3:0] = 0011.
not used
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 I
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 I
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 I
The GPIO2 pin is in Input mode. The input value is
stored in GP2_VAL.
The GPIO2 pin is in Open-drain mode. The output
value is determined by GP2_VAL.
The GPIO2 pin is in Output mode. The PLL output
clock divided by two is delivered.
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
