4.10.1 PORTH — Port H data register
4.10.2 DDRH — Data direction register for port H
4.11 Internal pull-up/pull-down resistors
MC68HC11P2 — Rev 1.0
Data direction H (DDRH)
Port H data (PORTH)
ups on pins 7–4 and pull-downs on pins 3–0 (see

This is a read/write register and is not affected by reset. The bits may be
read and written at any time, but, when a pin is allocated to its alternate
function, a write to the corresponding register bit has no affect on the pin
state.
DDH[7:0] — Data direction for port H
Three of the ports (B, F and G) have internal, software selectable pull-up
resistors. Port H has both pull-up and pull-down resistors, as described
below.
