Alt. Pin
Func.:
PGENx must be set to output the corresponding chip select signal. PGENx overrides DDGx.
MEM[1:0] select the memory expansion mode. Refer to the following table.
Port H has two bidirectional lines and shares functions with the PWM timer system. When a PWM timer
channel is enabled the corresponding port H pin becomes an output regardless of the state of the DDHx
bit. Refer to 9 Pulse-Width Modulation Timer.
Always read zero.
0 = Corresponding port G pin configured for output
1 = Corresponding port G pin configured for chip select function
0 = Input
1 = Output
