Port 0 Output Register (8-Bit Register)
This register is set to 7Fh on all forms of reset.
Unrestricted read/write.
Port 0 Output Register Bits [6:0]. This register stores output data for this port when it is defined as
an output port. Reading from the register returns the contents of the register and does not necessarily
reflect the true state of the port pins. Changing the direction of this port does not change the data con-
tents of the register.
Reserved. Read returns 0.
External Interrupt Flag 0 Register (8-Bit Register)
This register is cleared to 00h on all forms of reset.
Unrestricted read/write.
Interrupt Edge Detect Bits [2:0]. These bits are set when the edge selected by ITx is detected on the
interrupt pin, INTx. Setting any of the bits to 1 generates an interrupt to the CPU if the corresponding
interrupt is enabled. These bits remain set until cleared by software or a reset. It must be cleared by
software before exiting the interrupt source routine or another interrupt is generated as long as the bit
remains set.
Reserved. Read returns 0.
