Sales Demonstration Platform

The eZ80® Sales Demonstration Platform can be powered by the on-board batter­ies (stand-alone configuration) or by the AC adapter. Both configurations feature:

•

Serial communication using eZ80® UART ports and adapter board connectors

•

Ethernet communication using the eZ80L92 or eZ80F92 module

•

LCD displays relevant demo data

•

ZDI operation using external ZPAK

2

Caution:

Do not use battery power and AC power at the same time. Doing so will damage
the board.

WAIT PU 2k OUT Driving the WAIT pin Low forces the eZ80® CPU to

provide additional clock cycles for an external periph-

eral or external memory to complete its READ or

WRITE operation.

HALT_SLP

IN, Active Low A Low on this pin indicates that the eZ80® CPU

enters either HALT or SLEEP mode because of exe-

cution of either a HALT or SLP instruction.

NMI

PU 10K Schmitt Trigger

OUT, Active
Low

The NMI input is a higher priority input than the

maskable interrupts. It is always recognized at the

end of an instruction, regardless of the state of the

interrupt enable control bits. This input includes a

Schmitt trigger to allow RC rise times. This external

NMI

signal is combined with an internal NMI signal

generated from the WDT block before being con-
