Description
timer 0 output. Output. Depending on the
Timer Mode programmed for Timer 0, this
output can provide a single pulse or a
repetitive waveform.
timer 1 output. Output. Depending on the
Timer Mode programmed for Timer 1, this
output can provide a single pulse or a
repetitive waveform.
upper chip select. Output. Active Low. This
pin provides a chip select signal that will be
asserted (low) whenever the address of a
memory bus cycle is within the address space
programmed for that output.
Power (VCC). This pin provides power for the
IA188XL device. It must be connected to a
+5V DC power source.
Ground (VSS). This pin provides the digital
ground (0V) for the IA186XL. It must be
connected to a VSS board plane.
write. Output. Active Low. When asserted
(low), wr_n indicates that data available on
the data bus are to be latched into the
accessed memory or I/O device.
x1 and x2 are inputs for the crystal
