See the Terminal Functions section for pin details.

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.
