A/B
Channel A/Channel B (input) —
Write operation occurs.
CE
Chip Enable (input, active Low) —
operation.
D7–D0
Data Bus (bidirectional, tri-state) —
the SCC.
D/C
Data/Control Select (input) —
or from the SCC. A High indicates a data transfer; a Low indicates a command.
RD
Read (input, active Low) —
selected, enables the SCC’s bus drivers. During the Interrupt Acknowledge cycle, this
signal gates the interrupt vector onto the bus if the SCC is the highest priority device
requesting an interrupt.
WR
Write (input, active Low) —
operation. The coincidence of RD and WR is interpreted as a reset.
AD7–AD0
Address/Data Bus (bidirectional, active High, Tri-state) —
carry register addresses to the SCC as well as data or control information.
AS
Address Strobe (input, active Low) —
rising edge of this signal.
CS0
Chip Select 0 (input, active Low) —
addresses on AD7–AD0 and must be active for the intended bus transaction to occur.
