3.5.3 Peripheral Selection After Device Reset
After device reset, the PINMUX0 and PINMUX1 registers are software programmable to allow multiplexing
of shared device pins between peripherals, as given in the Terminal Functions section. Section 3.5.4,
Section 3.5.5, and Section 3.5.6 identify the register settings necessary to configure specific multiplexed
functions and show the primary (default) function after reset.
