3.6 Programmable Pull-Up/Pull Down Resistors

The Ports listed in the following table have 50 kOhm Pull-Up resistors, which can be enabled bit-wise. The
function is enabled by the Port Pull Enable Registers (PPER) and controlled by the Port Pull Control Register
(PPCR). The PPCR selects Pull-Up or Pull-Down. The Pull-Up/Pull-Down is disabled automatically in the STOP-
HiZ mode (STCR:STOP and STCR:HIZ set).
