Port Pull-up/pull-down Function

Each pin of ports P0 to P4 except P11 is equipped with a program-

mable pull-up transistor. P32/CRX and P40/KW0 to P47/KW7 are

equipped with programmable pull-down transistors as well. The

pull-up function of P0 to P3 can be controlled by the corresponding

port pull-up control registers (see Structure of port pull-up/down

control registers). The pull-up/down function of ports P32 and P4

can be controlled by the corresponding port pull-up/pull-down regis-

ters together with the polarity control register (see Structure of

polarity control register).
