I/O
Description
Clock source selection input
I
When ECKON = "High", External clock by CK pin is used as system clock, and internal
oscillator circuit is turned OFF. When ECKON = "Low", internal oscillator is used.
External clock input (When ECKON = "High")
I
It must be fixed "High" or "Low" when the internal oscillation circuit is used (When
ECKON = "Low").
MPU interface selection input
I
MI = "Low", 8080-series MPU
MI = "High", 6800-series MPU
COM direction selection input
When DIRC = "Low",
I
COM1 → COM2 - - - - → COM15 → COM16
When DIRC = "High",
COM16 → COM15 - - - - → COM2 → COM1
SEG direction selection input
When DIRS = "Low",
I
SEG1 → SEG2 - - - - → SEG79 → SEG80
When DIRS = "High",
SEG80 → SEG79 - - - - → SEG2 → SEG1
