Open Drain Control Register 0 (ODR0)
m = 1, 2, 7, 9, A, B, D
Bits corresponding to port m on the 48 pin-product but which do not exist on a product with fewer than 48 pins are
reserved. Write 0 to these bits.
The bits corresponding to a pin that does not exist or pins with no open-drain output allocation are reserved. A reserved
bit is read as 0. The write value should be 0.
