AIO_MUX1

The ten pins of AIO_MUX1 can be selectively mapped through a dedicated set of registers to 12 analog inputs for ADC1 peripheral, six analog inputs for Comparator peripherals, four General-Purpose Inputs, or four General-Purpose Outputs. While AIO_MUX1 has been named after the analog signals passing through it, the GPIOs (here called AIOs) are still digital, although with fewer features than those in the GPIO_MUX1 and GPIO_MUX2 blocks—for example, they do not offer pullups. On reset, all pins of the AIO_MUX1 block are configured as analog inputs and the GPIO function is disabled. The AIO_MUX1 block is programmed through a separate set of registers from those used to program AIO_MUX2.

The multiple registers responsible for configuring the AIO_MUX1 pins are accessible by the C28x CPU only. The top portion of Figure 8-17 shows Control Subsystem registers and muxing logic for the associated ten AIO pins. The AIOMUX1 register selects one of ten possible analog input signals or one of four general-purpose AIO inputs. Other registers allow reading and writing of the four AIO bits, as well as setting the direction for each of the bits (read or write). See Table 8-31 for the mapping of analog inputs and AIOs to the ten pins of AIO_MUX1.

AIO Mode 0 is chosen by setting selected odd bits of the AIOMUX1 register to ‘0’. AIO Mode 1 is chosen by setting selected odd bits of the AIOMUX1 register to ‘1’. For example, setting bit 5 of the AIOMUX1 register to ‘0’ assigns pin ADC1INA2 to internal signal AIO2 (digital GPIO). Setting bit 5 of the AIOMUX1 register to ‘1’ assigns pin ADC1INA2 to analog inputs ADC1INA2 or COMPA1 (only one should be enabled at a time in the respective analog module). Currently, all even bits of the AIOMUX1 register are “don’t cares”.

Blank fields represent Reserved functions.
For each field with two pins (for example, ADC1INA2, COMPA1), only one pin should be enabled at a time; the other pin should be disabled. Use registers inside the respective destination analog peripherals to enable or disable these inputs.
AIO Mode 0 represents digital general-purpose inputs or outputs.
AIO Mode 1 represents analog inputs for ADC1 or the Comparator module.
