Section 22 Pin Function Controller (PFC)
22.1.5 Port E Control Register (PECR)
PECR is a 32-bit readable/writable register that selects the pin functions. PECR is initialized to
H'00000000 by a power-on reset, and it is not initialized by a manual reset, in standby mode, or in
sleep mode.

R/W The combination of bits PEnMD2 and PEnMD1 (n = 0
R/W ^{to 15) controls the pin functions.}
00: Port input
R/W _{01: Port output}
R/W 10: Reserved (When set, correct operation cannot be
R/W
guaranteed.)
11: Other functions (see table 22.1.)
R/W _{When 11 (other functions) is set, the port E I/O register}
R/W (PEIOR) controls input or output. For details, see
R/W ^{section 22.1.6, Port E I/O Register (PEIOR).}
