Output
This pin can be used for GPIO. It can be
individually programmed as input or
output and can also be used individually
as an interrupt input. Each Port B pin,
when programmed as output, can be
selected to be an open-drain or
open-source output.
The MISO line is configured as an input
when the eZ80L92 MCU is an SPI master
device and as an output when eZ80L92
MCU is an SPI slave device. This signal is
multiplexed with PB6.
