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
5.6.6
Disabling N2HET Outputs
Some applications require the N2HET outputs to be disabled under some fault condition. The N2HET
module provides this capability via the "Pin Disable" input signal. This signal, when driven low, causes the
N2HET outputs identified by a programmable register (HETPINDIS) to be tri-stated. Please refer to the
device Terminal Reference Manual for more details on the "N2HET Pin Disable" feature.
GIOA[5] is connected to the "Pin Disable" input for N2HET1, and GIOB[2] is connected to the "Pin
Disable" input for N2HET2.
