(c) Port mode control register 6 (PMC6)
The PMC6 register is an 8-bit register that specifies the port mode or control mode (alternate
function).
Writing to the PMC6 register is only possible in a specific sequence, where a write access to the
command register (PRCMD) must be made before a write access to the PMC6 register is
accepted. A read operation in between the two write operations is allowed, i.e. read-modify-write is
possible on register PMC6. For details refer to 3.4.8
This register can be read or written in 8-bit or 1-bit units.
Reset input sets this register to 00H.
