(GPIOA2)
7
Output
In reset, PWMA2 — This is one of six PWMA output pins.

an input or output pin.
Output
In the 56F8323, the default state after reset is PWMA2.
PWMA3
(MISO1)
In the 56F8123, the default state is not one of the functions offered
and must be reconfigured.

Output
In reset, PWMA3 — This is one of six PWMA output pins.
output is
Schmitt disabled, SPI 1 Master In/Slave Out — This serial data pin is an input to a
Input/
pull-up is master device and an output from a slave device. The MISO line of a
Output
enabled slave device is placed in the high-impedance state if the slave device
is not selected. The slave device places data on the MISO line a
half-cycle before the clock edge the master device uses to latch the
data.
