(c) Port AL mode control register
The PMCAL register is a 16-bit read/write register that specifies the port mode or control mode
(alternate function) of Port AL.
This register can be read or written in 16-bit units.
If the higher 8 bits of the PMCAL register are used as PMCALH register, and the lower 8 bits as
the PMCALL register, however, these registers can be read or written in 8-bit or 1-bit units.
Reset input sets this register to 0000H in single-chip mode 0, and to FFFFH in ROM-less mode
and single-chip mode 1.
Caution:
On
μ
PD70F3447 do not set PMCALn bits to 1, since the corresponding alternate func-
tion is not available.
