HARDWARE CONSIDERATIONS
This section includes questions and answers on the hard-
ware interface, the clocks, the FIFO, special modes (Local
Loopback, DPLL, Manchester), and internal timing consid-
eration.
Hardware (Includes DMA Interface)
Q. What is the SCC transistor count?
A. Approximately 6000 gates, or 18,000 transistors.
Q. What is the difference between the Z8030 and the
A. The Z8030 and Z8530 are packaged from the same
Q. Can /AS be active only when the Z8030 is being ac-
A. Since the interrupt pending bits (IPs) are updated on
Q. How do /WR and /CE interact on the Z8530?
A. /WR and /CE are ANDed to enable a transparent latch.
Q. How many register pointers does the Z8530 have?
A. The SCC has only one register pointer for both chan-

bus (Z8530) version of the chip is selected at packag-
ing time by an internal bonding option.

address strobes, interrupts will not occur unless /AS is
continuous.
Data is latched on the falling edge when both /CE and
/WR go Low.
nels. The SIO (Z844X) has two, one for each channel.

Asychronous mode
These questions fall into the following five categories:

Q
Q. Do you have to write to the pointer with the Z8530
A. No. Both registers are accessed automatically without
Q. Does /CE (/CS) have to be High during an interrupt
A. No.
Q. Does the SCC support full duplex DMA?
A. The SCC allows full duplex DMA transfers by using the
Q. When using full duplex DMA, how do you program
A. W/REQ should be programmed for receive and
Q. Can both channels make simultaneous DMA
A. Yes.
Q. Do you have to reset the SCC in hardware?
A. No. A software reset is the same as a hardware reset,

is in shift right or shift left mode because the address
is the same in either.
