PDL (PDLH)
(PDLL)
After reset: 0000H (output latch) R/W Address:
PDL FFFFF004H,
PDLL FFFFF004H, PDLH FFFFF005H
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, they 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)

PMDL (PMDLH)
(PMDLL)
After reset: FFFFH R/W Address:
PMDL FFFFF024H,
PMDLL FFFFF024H, PMDLH FFFFF025H
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, they 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.
