the devices connected in expansion. In expansion mode one device will be
set as the Master, MAST input tied HIGH, all other devices will have MAST
tied LOW. The master device is the first device to take control of the
PAEnbus
and place the
PAE status of its queues onto the bus on the first rising edge of
RCLK after the
MRS input goes HIGH once a Master Reset is complete. The
ESYNC(
PAEsyncpulse)outputofthefirstdevice(masterdevice),willbeHIGH
for one cycle of RCLK indicating that it is has control of the
PAEn bus for that
cycle.
The device also passes a “token” onto the next device in the chain, the next
device assuming control of the
PAEnbusonthenextRCLKcycle.Thistoken
passing is done via the EXO outputs and EXI inputs of the devices (“
PAEn
Expansion Out” and “
PAEnExpansionIn”).TheEXOoutputofthefirstdevice

second device connects to the EXI of the third device and so on. The EXO of
