Output
This pin is be used for GPIO. It is
individually programmed as input or
output and is also used individually
as an interrupt input. Each Port B
pin, when programmed as output is
selected to be an open-drain or
open-source output.
The MISO line is configured as an
input when the eZ80F91 device is
an SPI master device and as an
output when eZ80F91 is an SPI
slave device. This signal is
multiplexed with PB6.
