PERIPHERAL RESOURCES
1. Parallel Ports
The MB90210 series has 57 I/O pins and 8 open-drain I/O pins.
Ports 0 to 5, 7, and 8 are I/O ports. Each of these ports serves as an input port when the data direction register
value is 0 and as an output port when the value is 1.
Port 6 is an open-drain port, which may be used as a port when the analog input enable register value is 0.
(1) Register Configuration
Port data registers 0 to 8 (PDR0 to PDR8)
Port direction registers 0 to 5, 7, and 8 (DDR0 to DDR5, DDR7, and DDR8)
