MOTOR CONTROLLER (Cont’d)
A
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:0 = AN[7:0]: A Weight Value.
These bits contain the A
tiplier. In autoswitched mode the MCOMP register
is automatically loaded with:
when a Z event occurs.
(*) depending on the DCB bit in the MCRA regis-
ter.
PRESCALER & SAMPLING REGISTER
(MPRSR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:4 = SA[3:0]: Sampling Ratio.
These bits contain the sampling ratio value for cur-
rent mode. Refer to Table 47, “Sampling Frequen-
cy Selection,” on page 189.
Bits 3:0 = ST[3:0]: Step Ratio.
These bits contain the step ratio value. It acts as a
prescaler for the MTIM timer and is auto incre-
mented/decremented with each R+ or R- event.
Refer to Table 40, “Step Frequency/Period Range
(4MHz),” on page 179
Accessing MTIM Timer-Related Registers,” on
page 179.

INTERRUPT MASK REGISTER (MIMR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = PUM: PWM Update Mask bit.
0: PWM Update interrupt disabled
1: PWM Update interrupt enabled
Bit 6 = SEM: Speed Error Mask bit.
0: Speed Error interrupt disabled
1: Speed Error interrupt enabled
Bit 5 = RIM: Ratio update Interrupt Mask bit.
0: Ratio update interrupts (R+ and R-) disabled
1: Ratio update interrupts (R+ and R-) enabled
Bit 4 = CLIM: Current Limitation Interrupt Mask bit.
0: Current Limitation interrupt disabled
1: Current Limitation interrupt enabled
This interrupt is available only in Voltage Mode
(VOC1 bit=0 in MCRA register) and occurs when
the Motor current feedback reaches the external
current limitation value.
Bit 3 = EIM: Emergency stop Interrupt Mask bit.
0: Emergency stop interrupt disabled
1: Emergency stop interrupt enabled
Bit 2 = ZIM: Back EMF Zero-crossing Interrupt
Mask bit.
0: BEMF Zero-crossing Interrupt disabled
1: BEMF Zero-crossing Interrupt enabled
Bit 1 = DIM: End of Demagnetization Interrupt
Mask bit.
