- 16-Bit Timer Counter
- [Pulse width measurement mode]
In the description of the pulse width measurement mode of the 16-bit timer counter, the following two corrections should be made regarding the INTTCA interrupt request generation timing.
1. The timing diagram for single-edge capture indicates that no interrupt request occurs at the first count start edge and the second count start edge after the timer is started. This should be corrected so that an interrupt request occurs at the first count start edge and the second count start edge, as shown below.
- Before correction
- After correction
2.The timing diagram for double-edge capture indicates that no interrupt request occurs at the count start edge after the timer is started. This should be corrected so that an interrupt request occurs at the count start edge, as shown below.
