7.6.11 Register 10 - Output port 0 register
7.6.12 Register 11 - Output port 1 register
This register is an output-only port. It reflects the outgoing logic levels of the pins defined
as outputs by Register 8. Bit values in this register have no effect on pins defined as
inputs. In turn, reads from this register reflect the value that is in the flip-flop controlling the
output selection, not the actual pin value.
