Pin Configurations
through
illustrate the pin configurations for all of the packages avail-
able in the Z8 Encore! XP
®
4K Series. Refer to
for a description of the signals.
The analog input alternate functions (ANAx) are not available on the Z8F041A, Z8F021A,
and Z8F011A devices. The analog supply pins (AV
DD
and AV
SS
) are also not available on
these parts, and are replaced by PB6 and PB7.
At reset, all Port A, B and C pins default to an input state. In addition, any alternate func-
tionality is not enabled, so the pins function as general purpose input ports until pro-
grammed otherwise. At powerup, the Port D0 pin defaults to the RESET alternate
function.
