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
Initial value
Read/Write
Bit 7 is reserved.
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, the corresponding pin maintains its output
state in software standby mode.

input port when these bits are cleared to 0.
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.
