INDUCTION MOTOR CONTROLLER (Cont’d)
TACHO
(TPRSH)
R244 - Read/Write
Register Page: 51
Reset Value: 0000 0000 (00h)
Bit 7:4 = Reserved.
Bit 3:0 = TPRH[3:0] Most Significant Bits of tacho
prescaler value (N).
TACHO PRESCALER REGISTER LOW (TPRSL)
R245 - Read/Write
Register Page: 51
Reset Value: 0000 0000 (00h)
Bit 7:0 = TPRL[7:0] Low byte of tacho prescaler
value (N).
If N = 0 Tacho Prescaler divides by 1.

PWM
(CPRS)
R246 - Read/Write
Register Page: 51
Reset Value: 0000 0000 (00h)
Bit 7:0 = CPR[7:0] PWM counter prescaler value
(N) .
This value divides the INTCLK frequency by (N
+1), i.e. if N = 0, INTCLK is divided by 1.
REPETITION COUNTER REGISTER (REP)
R247 - Read/Write
Register Page: 51
Reset Value: 0000 0000 (00h)
Bit 7:0 = REP[7:0] Repetition counter value (N).
If N = 0, each time the PWM Counter reaches ze-
ro, the Compare registers are updated and an
ADT interrupt is generated.
