Note: Due to internal synchronization circuits, it can take up to 2 bus clock cycles until the correct value is read
Port T — Port T bits 7–0 are associated with ECT channels IOC7–IOC0 (refer to ECT section). When not used
with the ECT, these pins can be used as general purpose I/O.
If the data direction bits of the associated I/O pins are set to logic level “1”, a read returns the value of the port
register, otherwise the buffered pin input state is read.
