I don't see a configuration entry for the Non-Maskable Interrupts (NMI) pins within SSP. How are they configured?
As of SSP 1.1.1 there is no configuration selection for the NMI pins within SSP. In order to configure the operation of these pins you must use the configuration registers directly. Refer to the MCU of interest Hardware Users Manual available from the Documentation Tab in on the Synergy MCU web page.
