Port1Ñ8-Bit Programmable I/O
Bank15/EXT1 is the Port1 control register. The MSB is the
Port1 direction control. Port1 data is accessed as the LSB
of EXT5 in Banks 0, 1, or 5. The Port1 pins can also be
mapped to internal functions. When INT2, CLKOUT, UI0

and UI1, or the SPI are enabled, they use Port1 pins. The
44-pin packages do not feature Port1 pins, however, Port1
and its internal functions can be mapped to the MSB of the
ED Bus/Port0 pins. See bits 2–0 of Bank15/EXT1.
