Pin Descriptions
Port signals
PORTH can be read at any time: inputs return the pin level; outputs
return the pin driver input level. If PORTH is written, the data is stored in
internal latches. The pins are driven only if they are configured as
outputs in single chip or bootstrap mode.
Port H pins include on-chip pull-up or pull-down devices that can be
enabled or disabled via the Port pull-up assignment register (PPAR).
Port H [7:4] have pull-up resistors; port H [3:0] have pull-down resistors.
For further information, refer to Parallel Input/Output, Serial
Communications Interface (SCI), Motorola Interconnect Bus
(MI BUS) and Timing System.
