PWM update interrupt flag

Current limitation interrupt flag
Emergency stop interrupt flag
BEMF zero-crossing interrupt flag
This bit is set by hardware when all the PWM compare register are transferred from
the preload to the active registers. The corresponding interrupt allows the user to
refresh the preload registers before the next PWM update event defined with MREP
register.
0: No PWM update interrupt pending
1: PWM update interrupt pending
Autoswitched mode (Swa bit = 1)
0: No R+ interrupt pending
1: R+ interrupt pending
Switched mode (Swa bit = 0)
0: No R+ action
1: The hardware increments the ST[3:0] bits when the next commutation occurs and
shifts all timer registers right.
Speed sensor mode (SWA bit = x, TES[1:0] bits = 01, 10, 11)
0: No R+ interrupt pending
1: R+ Interrupt pending
Autoswitched mode (SWA bit = 1)
0: No R- interrupt pending
1: R- Interrupt pending
Switched mode (SWA bit = 0)
0: No R- action
1: The hardware decrements the ST[3:0] bits when the next commutation occurs and
shifts all timer registers left
Speed sensor mode (SWA bit = x, TES[1:0] bits = 01, 10, 11)
0: No R- interrupt pending
