(b) Port mode register DL (PMDL)
This is a 16-bit register used to specify the input mode/output mode.
This register can be read and written only in 16-bit units.
However, when using the higher 8 bits of the PMDL register as the PMDLH register and the lower
8 bits as the PMDLL register, PMDL can be read and written in 8-bit and 1-bit units.
