23.4
Port E is a 7-bit input/output port with the pin configuration shown in figure 23.4. Each pin has an
input pull-up MOS, which is controlled by the port E control register (PECR) in the PFC.
23.4.1
Port E has the following register. Refer to section 27, List of Registers, for the address of this
register and state of this register in each processing mode.
• Port E data register (PEDR)
23.4.2
PEDR is a 7-bit readable/writable register that stores data for pins PTE6 to PTE0. Bits PE6DT to
PE0DT correspond to pins PTE6 to PTE0. 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.
