Bit 9
R/W
0x0

If the bit is set 1, when capturing channel 4 captures falling edge, it generates a capturing channel 4 pending.

0: Capture channel 4 fall lock interrupt disable
1: Capture channel 4 fall lock interrupt enable

  CRIE4

Bit 8
R/W
0x0

If the bit is set 1, when capturing channel 4 captures rising edge, it generates a capturing channel 4 pending.

0: Capturing channel 4 rise lock interrupt disable
1: Capturing channel 4 rise lock interrupt enable

  CFIE3

Bit 7
R/W
0x0

If the bit is set 1, when capturing channel 3 captures falling edge, it generates a capturing channel 3 pending.

0: Capturing channel 3 fall lock interrupt disable
1: Capturing channel 3 fall lock interrupt enable

  CRIE3

Bit 6
R/W
0x0

If the bit is set 1, when capturing channel 3 captures rising edge, it
generates a capturing channel 3 pending.
0: Capturing channel 3 rise lock interrupt disable
1: Capturing channel 3 rise lock interrupt enable

  CFIE2

Bit 5
R/W
0x0

If the bit is set 1, when capturing channel 2 captures falling edge, it generates a capturing channel 2 pending.
