These four signals are described below.
Disable Ethernet
When active Low, the DIS_ETH output signal disables the EMAC from
responding to CPU requests. As a result, additional inputs, outputs, or
memory devices can be used in the CS3 address space. The logic that dis-
ables the Ethernet signal is listed in
Disable Flash
When active Low, the DIS_Flash input signal disables the Flash chip on
the eZ80L92 Module.
Flash Write Enable
When active Low, the FlashWE input signal enables Write operations on
the Flash boot block of the eZ80L92 Module.
Disable IrDA
When the DIS_IrDA input signal is pulled Low, the IrDA transceiver,
located on the eZ80L92 Module, is disabled. As a result, UART0 can be
used with the RS232 or the RS485 interfaces on the eZ80
Platform.
An Application Module Interface is provided to allow the user to add an
application-specific module to the eZ80
Thermostat Application Module (not provided in the kit) is an example
application-specific module that demonstrates an HVAC control system.
