Section 18 I/O Ports
18.5.2
Port E data register (PEDR) is an 8-bit read/write register that stores data for pins PTE7 to PTE0.
PE7DT to PE0DT bit corresponds to PTE7 to PTE0 pin. When the pin function is general output
port, if the port is read the value of the corresponding PEDR bit is returned directly. When the
function is general input port, if the port is read the corresponding pin level is read.
PEDR is initialized to H'00 by a power-on reset, after which the general input port function (pull-
up MOS on) is set as the initial pin function, and the corresponding pin levels are read. It retains
its previous value in standby mode and sleep mode, and in a manual reset.
