PWM output
The PWM output unit may behave erroneously if the condition for changing the PWM output (EQUx or EQU0) and the condition for loading the shadow register TBCLx happen at the same time. Depending on the load condition for the shadow registers (CLLD bits in TBCCTLx), there are four possible error conditions:
1. Change CCRx register from any value to CCRx = 0 (for example, sequence for CCRx = 4 3 2 0 0 0)
2. Change CCRx register from CCRx = 0 to any value (for example, sequence for CCRx = 0 0 0 2 3 4)
3. Change CCRx register from any value to current SHD0 (CCR0) value (for example, sequence for CCRx = 4 2 5 SHD0 3 8)
4. Change CCRx register from current SHD0 (CCR0) value to any value (for example, sequence for CCRx = 4 2 SHD0 5 3 8)
No general workaround available.
