Table 9.11 shows the port 6 register configuration.
Table 9.11 Port 6 Registers
Note:
Port 6 Data Direction Register (P6DDR)
P6DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 6. P6DDR cannot be read; if it is, an undefined value will be read.
Setting a P6DDR bit to 1 makes the corresponding port 6 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P6DDR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode. As the DMAC is initialized by a
manual reset, the pin states are determined by the P6DDR and P6DR specifications.
