6.5. I/O Ports : PORT1[7:0]
Open-drain or push-pull output, pull-up control, ADC input.
The alternative functions are available only when the corresponding SFR bit is “1”.
Read-Modify-Write instructions do not read port pin but the port SFR.
0 = Push-pull Output / 1 = Open-drain Output (Default)
0 = Output (Default) / 1 = Input
0 = Pull-up resistor ON (Default) / 1 = OFF
0 = ADC0 channel ON / 1 = ADC0 channel OFF (Default)
