MOTOR CONTROLLER (Cont’d)
PARITY REGISTER (MPAR)

Reset Value: 0000 0000 (00h)
Bits 7:6 = TES[1:0] : Tacho Edge Selection bits
The primary function of these bits is to select the
edge sensitivity of the tachogenerator capture log-
ic; clearing both TES[1:0] bits specifies that the In-
put Detection block does not operate in Speed
Sensor Mode but either in Position Sensor or Sen-
sorless Mode for a six-step motor drive).

Bits 5:0 = OE[5:0]: Output Parity Mode.
0: Output channel is High
1: Output channel Low
Note: These bits are not significant when PCN=1
(configuration with three independent phases).
