PRODUCTION DATA.
N2HET1[31] is connected as a clock source for counter 1 in DCC1. This allows the application to measure the frequency of the pulse-width modulated (PWM) signal on N2HET1[31].
Similarly, N2HET2[0] is connected as a clock source for counter 1 in DCC2. This allows the application to measure the frequency of the pulse-width modulated (PWM) signal on N2HET2[0].
Both N2HET1[31] and N2HET2[0] can be configured to be internal-only channels. That is, the connection to the DCC module is made directly from the output of the N2HETx module (from the input of the output buffer).
For more information on DCC see Section 5.7.3.
