Port E control register L (PECRL) is a 16-bit readable/writable register that selects the functions
of pins in port E.
PECRL selects the functions of port E pins PE15/IRQ7 to PE12/IRQ4.
PECRL is initialized to H'0000 by an external power-on reset, but is not initialized by a WDT
reset, in standby mode, or in sleep mode.
Bit 15—Reserved: This bit is always read as 0 and should only be written with 0.
Bit 14—PE15 Mode (PE15MD): Selects the function of the PE15/IRQ7 pin.
Bit 14: PE15MD
