4.3.7.2
Read: Anytime. Write: Never, writes to this register have no effect.
If the associated slew rate control is enabled (digital input buffer is disabled), a read returns a “1”. If the
associated slew rate control is disabled (digital input buffer is enabled), a read returns the status of the
associated pin.
4.3.7.3
Read: Anytime. Write: Anytime.
This register configures port pins PU[7:0] as either input or output.
When enabled, the SSD or MC modules force the I/O state to be an output for each associated pin and the
associated Data Direction Register bit has no effect. If the SSD and MC modules are disabled, the
corresponding Data Direction Register bits revert to control the I/O direction of the associated pins.
