11.4.2.1 Port Output Data Registers
MMC2107 – Rev. 2.0
MOTOROLA
Address: 0x00c0_0000 — PORTA
This subsection provides a description of the I/O port registers.
The port output data registers (PORTx) store the data to be driven on the
corresponding port x pins when the pins are configured for digital output.
Reading PORTx returns the current value in the register, not the port x
pin values.
The SETx and CLRx registers also affect the PORTx register bits. To set
bits in PORTx, write 1s to the corresponding bits in PORTxP/SETx. To
clear bits in PORTx, write 0s to the corresponding bits in CLRx.
PORTx are read/write registers when not in emulation mode. Reset sets
PORTx.
