Table 23-39. N2HET Open Drain Register (HETPDR) Field Descriptions
Bit Field Value Description
31-0 HETPDR[n] Open drain control for HET[n] pins
0 The pin is configured in push/pull mode.
1 The pin is configured in open drain mode. The HETDOUT register controls the state of the output
buffer:
HETDOUT[n] = 0 The output buffer of pin HET[n] is driven low.
HETDOUT[n] = 1 The output buffer of pin HET[n] is tristated.
23.4.24 N2HET Pull Disable Register (HETPULDIS)
Values in this register enable or disable the pull-up/-down functionality of the pins.
