Port E is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in units of
bits. Outputs can be set by using the function register PEFC1 and the control register PECR. A reset allows all
bits of the output latch PE, PECR and PEFC1 to be cleared to "0," and the port E to be put in output disable
mode.
Besides the input/output port function, the port E performs other functions: PE0 through PE4 output a 16-bit
timer, PE5 and PE6 have I2C function and PE5 through PE7 have SIO function.
