Pin Configurations
Figures 2 and 4 illustrate the pin configurations for all of the packages available in the Z8
Encore! XP® F08xA Series. Refer to Table 3 for a description of the signals. The analog
input alternate functions (ANAx) are not available on the Z8F081A devices. The analog
supply pins (AVDD and AVSS) 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.
The pin configurations listed are preliminary and subject to change based on manufactur-
ing limitations.
