I/O Ports
(1) Outline of I/O ports
Each I/O port outputs data from the CPU to the I/O pins or inputs signals from the I/O pins to the CPU as directed
by the port data register (PDR) . Each CMOS I/O port can also designate the direction of a data flow (input or
output) at the I/O pins in bit units using the port data direction register (DDR) . Or N-channel open-drain port
can designate the direction of a data flow (input or output) at the I/O pins in bit units using the port data register
(PDR) . The function of each port and the resources using it are described below :
Port 0
Port 1
Port 2
Port 3
Port 4
Port 5
Port 6
Port 7
Port 8
Port 9

: General-purpose I/O port/resource (LCD controller*)
* : LCD controller doesn’t exist in MB90F377, and so Port E and F of MB90F377 are not used for this purpose.
