PIN FUNCTIONS
R/
RL
(input, active Low).
The ROM/ROMless pin, when
connected to
GND
, disables the internal ROM and forces
the device to function as a ROMless Z8. (Not available for
devices in the 28-pin package.)
Notes:
When left unconnected or pulled High to
V
CC
, the
device functions normally as a Z8 ROM version.
When using in ROM Mode in a high-EMI (noisy)
environment, the ROMless pins should be connected
directly to
V
CC
.
DS
(output, active Low).
Data Strobe is activated one
time for each external memory transfer. For a
READ
oper-
ation, data must be available prior to the trailing edge of
DS
.
For
WRITE
operations, the falling edge of
DS
indicates that
output data is valid. (Not available for devices in the 28-
pin package.)
AS
(output, active Low).
Address Strobe is pulsed one
time at the beginning of each machine cycle for external
memory transfer. Address output is from Port 0/Port 1 for
all external programs. Memory address transfers are valid
at the trailing edge of
AS
. Under program control,
AS
is
placed in the high-impedance state along with Ports 0 and
1, Data Strobe, and
READ/WRITE
. (Not available for de-
vices in the 28-pin package.)
XTAL1 Crystal 1 (time-based input).
This pin connects a
parallel-resonant crystal, ceramic resonator,
LC
, or
RC
net-
work, or an external single-phase clock to the on-chip os-
cillator input.
XTAL2 Crystal 2 (time-based output).
This pin connects
a parallel-resonant crystal, ceramic resonant,
LC
, or
RC
net-
work to the on-chip oscillator output.
R/
W
(output, WRITE Low).
The
READ/WRITE
signal is
Low when the Z8 is writing to the external program or data
memory. (Not available for devices in the 28-pin package.)
