6.5.11.1 nERROR and nERROR1 Input Multiplexing

There are two ESM modules in this microcontroller. When the microcontroller is in lockstep mode, only

ESM1 is active.

By default, the ESM1 Error Pin Status Register (ESMEPSR) samples the nERROR pin input. The default

is achieved with PINMMR174[16] = 1. By setting PINMMR174[16] = 0, the ESM1 Error Pin Status register

will sample from the nERROR1 pin instead as illustrated in Figure 6-8.
