I/O
Input: Independently connect to EV
DD0, EVDD1 or EVSS0, EVSS1
via a resistor.
Output: Leave open.
Remarks 1. With products not provided with an EVDD0, EVDD1, EVSS0, or EVSS1 pin, replace EVDD0 and EVDD1 with VDD, or
replace EV
SS0 and EVSS1 with VSS.
2. Functions in parentheses in the above figure can be assigned via settings in the peripheral I/O redirection
register (PIOR).
