Input
External Interrupt Request A — The IRQA input is an
asynchronous external interrupt request during Stop and Wait
mode operation. During other operating modes, it is a
synchronized external interrupt request which indicates an
external device is requesting service. It can be programmed
to be level-sensitive or negative-edge-triggered
VPP — This pin is used for Flash debugging purposes.
