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