Function
Data bus: Three-state I/O common terminal
Data is transferred to MPU through DB0 to DB7.
Chip select: Selected state with
CS
= 0
Read/Write:R/W = 1: MPU

HD61830
Register select:RS = 1: Instruction register
RS = 0: Data register
Enable: Data is written at the fall of E
Data can be read while E is 1
CR oscillator (HD61830), External clock input (HD61830B)
CR oscillator to capacitor (HD61830 only)
CR oscillator to resistor (HD61830 only)
Clock signal for HD61830 in slave mode (HD61830 only)
Chip enable (HD61830B only)
CE
= 0: Chip enables make external RAM in active
Output enable (HD61830B only)
OE
= 1: Output enable informs external RAM that HD61830B requires
data bus
