Signal Description
3.4.2 INT Signal Functions
3.4.3 Serial Peripheral Interface (SPI) Pin Functions
Advance Information
110
NOTE:
The INT signals have these multiple functions:
If the SZEN or PSTEN bits are set during emulation mode, then the
corresponding edge port INT functions are lost and will not be emulated
externally.
The default reset value for the PUPSC1 bit in SCIPURD is 0. Thus, the
pullup function is disabled by default.
The SPI module can support up to eight external pins, but only the four
pins required for the SPI interface are implemented.
Full SPI interface capabilities and GPIO functions using the MISO,
MOSI, SCK, and SS pins are supported.

For More Information On This Product,
If the SZEN bit in the Chip Configuration Register is set, then
INT[7:6] will be used to reflect the state of the TSIZ[1:0] signals
from the CPU. See
If the PSTEN bit in the Chip Configuration Register (CCR) is set,
then INT[5:2] will be used to reflect the state of the PSTAT[3:0]
signals from the CPU. See
SWOM register bit controls whether output buffers behave as
open-drain outputs. Default is not open-drain outputs.
PUPSP0 register bit enables internal weak pad pullup devices.
Default is pullups disabled.
RDPSP0 register bit controls reduced drive function of output
buffers. Default is full drive.
