JTAG Data Input pin.
V
Active High trigger event indicator.
JTAG Input. High on reset enables ZDI mode;
Low on reset enables OCI debug.
JTAG Test Mode Select Input.
RTC supply. For proper operation of the Zdots,
this pin must be connected to the same power
source that powers the module (as it is done on
the Zilog
Synchronous CPU clock output.

A Low enables a Write to external Flash memory
boot block area. If this pin is unconnected, the
Flash memory boot block area is Write-protected.
V
Used on the eZ80190, eZ80L92, eZ80F92,
eZ80F93 devices and connected to the CS8900
EMAC.
A Low disables the onboard IRDA transceiver to
use PC0/PC1 UART pins externally.
Reset Output from module or push-button reset.
Driving the WAIT pin Low forces the CPU to
provide additional clock cycles for an external
peripheral or external memory to complete its
Read or Write operation.
