Bit Field Value Description
31-0 HETDSET[n] This register allows bits of HETDOUT to be set while avoiding the pitfalls of a read-modify-write
sequence in a multitasking environment.
Bits written as a logic 1 set the same bit in the HETDOUT register; while bits written as logic 0
leave the same bit in HETDOUT unchanged. Reads from this address return the value of the
HETDOUT register.
0 Write: HETDOUT[n] is unchanged.
1 Write: HETDOUT[n] is set.

Bit Field Value Description
31-0 HETDCLR[n] This register allows bits of HETDOUT to be cleared while avoiding the pitfalls of a read-modify-write
sequence in a multitasking environment.
Bits written as a logic 1 clear the same bit in the HETDOUT register; while bits written as logic 0
leave the same bit in HETDOUT unchanged. Reads from this address return the value of the
HETDOUT register.
0 Write: HETDOUT[n] is unchanged.
1 Write: HETDOUT[n] is cleared.
