Caution Be sure to set (1) the interrupt mask flag (TMMK50) before clearing (0) TCE50 to avoid generating
Remarks 1. The PWM output is at the inactive level in the PWM mode because TCE50 = 0.
TMC50
Symbol
an interrupt when TCE50 is cleared. The procedure to clear (0) TCE50 is as follows.
TMMK50 = 1
TCE50 = 0
TMIF50 = 0
TMMK50 = 0
TCE50 = 1
2. If LVS50 and LVR50 are read immediately after data has been set, these bits are 0.
