(P3L)
Remarks 1. The P3 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the P3 register as the P3H register and the
lower 8 bits as the P3L register, P3 can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the P3 register in 8-bit or 1-bit units, specify them as bits 0 to
7 of the P3H register.
