MOTOR CONTROLLER (Cont’d)
MOTOR CURRENT FEEDBACK REGISTER
(MCFR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7= RPGS: Register Page Selection:
0: Access to registers mapped in page 0
1: Access to registers mapped in page 1
Bit 6= RST: Reset MTC registers.
Software can set this bit to reset all MTC registers
without resetting the ST7.
0: No MTC register reset
1: Reset all MTC registers
Bits 5:3 = CFF[2:0]: Current Feedback Filter bits
These bits select the number of consecutive valid
samples (when the current is above the limit)
needed to generate the active event. Sampling is
done at f

Bits 2:0 = CFW[2:0]: Current Window Filter bits:
These bits select the length of the blanking win-
dow activated each time PWM is turned ON. The
filter blanks the output of the current comparator.
