Is it possible to use the MSP432E401Y for center-aligned SVPWM waveform generation? This is in light of the following Errata from SLAZ709:
*********************************
PWM#05 Generator load with global sync may lead to erroneous pulse width
Description There is a condition where the generator timer may still count with the old value, but the
new comparator value gets loaded causing an erroneous high pulse width.
Workaround The application must use the interrupt status to write the value of the new load and
comparator values. When using the down count mode, clear the raw interrupt status bit
for the respective comparator down count match interrupt status bit, wait for it to be set
again and then update the new value for the load and comparator match.
PWM#06 PWM output may generate a continuous high instead of a low or a continuous low
instead of high
Description When using PWM in UP-DOWN count mode, the PWM generator may generate a
continuous High instead of Low or continuous Low instead of High under the following
condition:
• The PWM generator is used with action for comparator A or B UP and DOWN to
control the PWM cycle.
• The PWM comparator A or B is changed from a count of 2 or more to PWM Load
Count value.
• A continuous High is generated if the invert option is enabled.
• A continuous Low is generated if the invert option is disabled.
Workaround
• Use DOWN count mode of PWM
• When changing from any value (other than 1) to the PWM load count value in the
Comparator Load Register, always go to value of 1 before going to the PWM load
count value.
