RX23W Group 21. I/O Ports
21.3.2 Port Output Data Register (PODR)
m = 0 to 4, B to E, J
PODR holds the data to be output from the pins used for general output ports.
Bits corresponding to port m on the 85 pin-product but which do not exist on a product with fewer than 85 pins are
reserved. Write 0 to these bits.
The B2 and B3 bits of PORT1.PODR, B0 bit of PORT2.PODR, and B2, B3, and B4 bits of PORT3.PODR register are
reserved. Values read from reserved bits are undefined. When writing, read the register and then rewrite the values that
were read to the reserved bit or bits.
The PORT3.PODR.B5 bit is reserved, because the P35 pin is input only. The bit corresponding to a pin that does not exist
is reserved. A reserved bit is read as 0. The write value should be 0.
Address(es): PORT0.PODR 0008 C020h, PORT1.PODR 0008 C021h, PORT2.PODR 0008 C022h, PORT3.PODR 0008 C023h,
PORT4.PODR 0008 C024h, PORTB.PODR 0008 C02Bh, PORTC.PODR 0008 C02Ch, PORTD.PODR 0008 C02Dh,
