17.5
For SPI, an interrupt request is generated after a byte is
received or transmitted. See Section
21.3 for details on the SPI
interrupt.
SPI Interrupt
17.6
The GPIO pins used for SPI outputs (P0.5–P0.7) contain a
bypass mode, as shown in the GPIO block diagram
(
Figure 12-1
). Whenever the SPI block is inactive (Mode[5:4]
= 00), the bypass value is 1, which enables normal GPIO
SPI Modes for GPIO Pins
operation. When SPI master or slave modes are activated, the
appropriate bypass signals are driven by the hardware for
outputs, and are held at 1 for inputs.
Note that the corre-
sponding data bits in the Port 0 Data Register must be set
to 1 for each pin being used for an SPI output.
In addition,
the GPIO modes are not affected by operation of the SPI
block, so each pin must be programmed by firmware to the
desired drive strength mode.
For GPIO pins that are not used for SPI outputs, the SPI
bypass value in
Figure 12-1
is always 1, for normal GPIO
operation.
