2.
2. n = 0 to 15
To read/write bits 8 to 15 of the PUDL register in 8-bit or 1-bit units, specify them as bits 0 to 7 of
the PUDLH register.
An on-chip pull-up resistor can be connected only when the pins are in input mode in the port
mode. An on-chip pull-up resistor cannot be connected when the pins are in output mode.
When the higher 8 bits of the PUDL register are used as the PUDLH register, and the lower 8
bits, as the PUDLL register, these registers can be read or written in 8-bit or 1-bit units.
