Description
It determines how the general purpose pin GPIO2 is
configured.
Description
reserved, must be set to logic 000
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 HVPLL signal is chosen according to
Table
