6. I/O Ports
The MCU provides 5 bi-directional I/O ports plus 1 CMOS open drain output port (PORTE.1). The PORT data put in register
($08 - $0C). The PORT control register ($18 - $1C) controls the PORT as input or output. Each I/O port (excluding those
open drain output ports) contains a pull-high resistor, which is controlled by the value of the corresponding bit in the port
pull-high control register ($388 - $38C), independently.
When the port is selected as an input port, write “1” to the relevant bit in the port pull-high control register ($388 - $38C),
could turn on the pull-high resistor and write “0” could turn off the pull-high resistor.
When the port is selected as an output port, the pull-high resistor will be turned off automatically, regardless the value of
the corresponding bit in the port pull-high control register ($388 - $38C).
When PORTB/D are selected as the digital input direction, they can active port interrupt by falling edge (if port interrupt is
enabled).
