Input Cycle
During the Input Cycle, the falling edge of AEN
causes the state of each selected pin to be trans-
ferred to EEDO (that is, EEDO will be high or
low depending on the input level of the selected
pin). This cycle begins with SLEEP and ad-
vances clockwise through each of 37 input pins
(all digital input pins except for AEN) and each
of the 16 bi-directional pins, one pin at a time.
The following is a list of input pins and bi-direc-
tional pins that are tested during the Input Cycle:

After the Input Cycle is complete, one more cy-
cle of AEN returns all digital output pins and
bi-directional pins to a high-impedance state.
Continuity Cycle
The combination of a complete Output Cycle, a
complete Input Cycle, and an additional AEN cy-
cle is called a Continuity Cycle. Each Continuity
Cycle lasts for 85 AEN clock cycles. The first
Continuity Cycle can be followed by additional
Continuity Cycles by keeping TEST low and
continuing to cycle AEN. When TEST is driven
high, the CS8920A exits Boundary Scan mode
and AEN is again used as the ISA-bus Address
Enable.
Figure 6.1 shows a complete Boundary Scan
Continuity Cycle.
Figure 6.2 shows Boundary Scan timing.
