MOTOR CONTROLLER (Cont’d)

PARITY REGISTER (MPAR)

Read/Write

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).

Table 79. Tacho edges and input mode selection

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).
