DESCRIPTION

Reads are indeterminate. Only 0s should be written to these bits.

AMUTEIN2 Selects the source of the input to the McASP2 mute input. 000 = Select the input to be a constant '0'

001 = Select the input from AXR0[7]/SPI1_CLK

010 = Select the input from AXR0[8]/AXR1[5]/SPI1_SOMI

011 = Select the input from AXR0[9]/AXR1[4]/SPI1_SIMO

100 = Select the input from AHCLKR2

101 = Select the input from SPI0_SIMO

110 = Select the input from SPI0_SCS/I2C1_SCL

111 = Select the input from SPI0_ENA/I2C1_SDA
