Description
This pin can be used for general-purpose I/
O. 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.
Programmable Reload Timer 4 timer-out
signal. This signal is multiplexed with PB4.

Programmable Reload Timer 5 timer-out
signal. This signal is multiplexed with PB5.
This pin can be used for general-purpose I/
O. 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.
