IMUX Select Register 2 (SIU_ISEL2)
The SIU_ISEL2 register specifies the source for the eMIOS[15:0] input channels, thus allowing the timer
input channels to come from the pins, or from the deserialized output of one of three DSPI modules. Each
2-bit field in this register individually controls the setting for one eMIOS input channel, but typically all
channels receive their inputs from the same source.
ESEL1
External IRQ Input Select 1. Specifies input for IRQ1.
