NOTE

If ADEVT, N2HET1 or GIOB is used as a trigger source, the connection to the MibADC1

module trigger input is made from the output side of the input buffer. This way, a trigger

condition can be generated either by configuring the function as output onto the pad (through

the mux control), or by driving the function from an external trigger source as input. If the

mux control module is used to select different functionality instead of the ADEVT, N2HET1[x]

or GIOB[x] signals, then care must be taken to disable these signals from triggering

conversions; there is no multiplexing on the input connections.

N2HET1[11], N2HET1[17] or N2HET1[19] is used to trigger the ADC the connection

to the ADC is made directly from the N2HET or ePWM module outputs. As a result,

the ADC can be triggered without having to enable the signal from being output on

a device terminal.

NOTE

For the RTI compare 0 interrupt source, the connection is made directly from the output of

the RTI module. That is, the interrupt condition can be used as a trigger source even if the

actual interrupt is not signaled to the CPU.
