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.

GPAAMSEL is shown in Figure 8-12 and described in Table 8-20.

Return to the Summary Table.

GPIO A Analog Mode Select register (GPIO0 to GPIO31)

Selects between digital and analog functionality for GPIO pins.

0: The analog function of the pin is disabled and the pin is capable of digital functions as specified by the other GPIO configuration registers
1: The analog function of the pin is enabled and the pin is capable of analog functions

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

Note:
[1] This register and bits are only valid for GPIO signals that share analog function through a unified I/O pad. For all the IOs, the corresponding bits in these registers dont have any affect.
