MB90610A Series
s PERIPHERAL RESOURCES
1. Parallel Port
The MB90610A series has 58 I/O pins, 18 output pins, and 8 open drain output pins.
Ports 1 to 5 and ports 7 to A are I/O ports. The ports are inputs when the corresponding direction register bit is
“0” and outputs when the corresponding bit is “1”.
Port 1 is only available when the external data bus is in 8-bit mode. Access is prohibited in 16-bit mode.
Ports 2 and 3 are only available when the address/data bus is in multiplex mode. Access is prohibited in non-
multiplex mode.
Port 6 is an open drain port. Port 6 pins can only be used as ports when the analog input enable register is “0”.
(1) Register Configuration
Notes: No register bits are provided for bit 6 to 7 of port 5.
No register bit is provided for bit 7 of port 7.
No register bit is provided for bit 7 of port 8.
No register bits are provided for bits 6 to 7 of port 9.
No register bit is provided for bit 0 of port A.
