14.3.10 Port E Control Register 2 (PECR2)
Port E control register 2 (PECR2) is a 16-bit readable/writable register that selects the functions of
the pins in port E.
PECR2 is initialized to H'0000 by an external power-on reset. However, it is not initialized by a
WDT reset, in standby mode, or in sleep mode. In these cases it retains its previous data.
