Port 6 Data Direction Register (P6DDR)
P6DDR is an 8-bit write-only register that can select input or output for each pin in port 6. Bit 7 is
reserved. It cannot be modified and is always read as 1.
Modes 1 to 6 (Expanded Modes): Ports P6
HWR, RD, AS), regardless of the settings of P6
bus control pins (BACK, BREQ, WAIT) or I/O ports. For selecting the pin function, see table
9.11. When ports P6
of port 6 functions as an output port. If P6DDR is cleared to 0, the corresponding pin functions as
an input port.
Mode 7 (Single-Chip Mode): Port 6 is a generic input/output port. A pin in port 6 becomes an
output port if the corresponding P6DDR bit is set to 1, and an input port if this bit is cleared to 0.
P6DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P6DDR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P6DDR bit is set to 1 while port 6 acts as an I/O port, the
corresponding pin maintains its output state in software standby mode.
