MIBSPI3NCS[3]/I2C_SCL/N2HET1[29]/nTZ1 3 Input Pull Up Fixed 20 µA Trip Zone Inputs 1, 2 and
Pull Up 3. These signals are
MIBSPI3NCS[2]/I2C_SDA/N2HET1[27]/nTZ2 4
either connected
N2HET1[10]/nTZ3 118 Pull Down
asynchronously to the
ePWMx trip zone inputs,
or double-synchronized
with VCLK4, or double-
synchronized and then
filtered with a 6-cycle
VCLK4-based counter
before connecting to the
ePWMx trip zone inputs.

GIOB[3] 1 Pull Down
(1) GIOB[2] cannot output a level on to pin 55. Only the input functionality is supported so that the application can generate an interrupt
whenever the N2HET2_PIN_nDIS is asserted (driven low). Also, a pull up is enabled on the input. This is not programmable using the
GIO module control registers.
