Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
Status Flag Clearing Timing: After a status flag is read as 1 by the CPU, it is cleared by writing
0 to it. When the DTC/DMAC is activated, the flag is cleared automatically. Figures 11.115 and
11.116 show the timing for status flag clearing by the CPU, and figures 11.117 to 11.119 show the
timing for status flag clearing by the DTC/DMAC.
