Register Array Variables
i,j,k,l,m,nWhen these variables are used in a register name, an offset, or an address, they refer to the value of a register array where the register is part of a group of repeating registers. The register groups form a hierarchical structure and the array is represented with a formula.
yWhen this variable is used in a register name, an offset, or an address it refers to the value of a register array.

GPIO B Open Drain Output Register (GPIO32 to GPIO63)

Selects between normal and open-drain output for the GPIO pin.

0: Normal Output
1: Open Drain Output

Reading the register returns the current value of the register setting.

Note:
[1] In the Open Drain output mode, if the buffer is configured for output mode, a 0 value to be driven out comes out on the on the PAD while a 1 value to be driven out tri-states the buffer.
