(2) Control registers
(a) Port register 6 (P6)
The P6 register is an 8-bit register that controls reading the pin levels and writing the output levels
of port pins P60 to P67.
Writing to the P6 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 P6 register is accepted. A
read operation in between the two write operations is allowed, i.e. read-modify-write is possible on
register P6. For details refer to 3.4.8
This register can be read or written in 8-bit or 1-bit units.
Reset input causes an undefined register content.
After reset: Undefined

(b) Port mode register 6 (PM6)
The PM6 register is an 8-bit register that specifies the input or output mode.
Writing to the PM6 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 PM6 register is accepted.
A read operation in between the two write operations is allowed, i.e. read-modify-write is possible
on register PM6. 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 FFH.
After reset: FFH
