Figure 8-16. Control Register Settings for Pulse Width Measurement by Restarting
(a) 16-bit timer mode control registers 0, 1, 7 to 12 (TMC0, TMC1, TMC7 to TMC12)
TMCn 0 0
(b) Capture/compare control registers 0, 1, 7 to 12 (CRC0, CRC1, CRC7 to CRC12)
CRCn 0 0
Remarks 1. 0/1: When these bits are reset to 0 or set to 1, other functions can be used along with the pulse
width measurement function. For details, refer to 8.1.4 (1) 16-bit timer mode control
registers 0, 1, 7 to 12 (TMC0, TMC1, TMC7 to TMC12) and (2) Capture/compare control
registers 0, 1, 7 to 12 (CRC0, CRC1, CRC7 to CRC12).
2. n = 0, 1, 7 to 12
