PDL (PDLH)
(PDLL)
Remarks 1. The PDL register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PDL register as the PDLH register and the
lower 8 bits as the PDLL register, PDL can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the PDL register in 8-bit or 1-bit units, specify them as bits 0
to 7 of the PDLH register.
(2) Port DL mode register (PMDL)
PMDL7

PMDL (PMDLH)
(PMDLL)
Remarks 1. The PMDL register can be read or written 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 or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the PMDL register in 8-bit or 1-bit units, specify them as bits
0 to 7 of the PMDLH register.
