5	TX5MASK	0-1	Transmit channel 5 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.

4	TX4MASK	0-1	Transmit channel 4 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.

3	TX3MASK	0-1	Transmit channel 3 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.

2	TX2MASK	0-1	Transmit channel 2 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.

1	TX1MASK	0-1	Transmit channel 1 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.

0	TX0MASK	0-1	Transmit channel 0 interrupt mask set bit. Write 1 to enable interrupt, a write of 0 has no effect.
