The PEPA and PCDPA bits in the ports must also be set to 1 to obtain
full visibility. The waveforms shown in
cycles.
The show strobe (SHS) pin provides an indication to an external device
(emulator or logic analyzer) when to latch address, TC[2:0], TSIZ[1:0],
R/W, CSE, PSTAT, and data from the external pins. In master and
emulation modes, show cycle strobe (SHS) is enabled coming out of
reset. In master mode this default functionality can be overridden to
make the pin function as digital I/O.
For any external cycle or show cycle, the SHS pin is driven low to
indicate valid address, TC, TSIZ, R/W, CSE, and PSTAT are present at
the pins, and driven back high to indicate valid data. The SHS pin is
driven low and back high only once per external bus cycle. See
