CMR (x0CMR, x1CMR, x2CMR, x3CMR)
:
The CMR is a write only register, which when written into,
generates transient signals to perform load and reset operations
as described below:
CMR: B7 B6 B5 B4 B3 B2 B1 B0
B0 = 0: Nop
= 1: Reset CNTR and sign to 0.
(Should not be combinedwith load_CNTR
operation).
B1 = 0: Nop
= 1: Load CNTR from PR. Affects all 24 bits. (Should
not be combined with reset_CNTR operation)
B2 = 0: Nop
= 1: Load OL from CNTR. Affects all 24 bits.
B3 = 0: Nop
= 1: Reset STR. Affects status bits corresponding to
carry, borrow, compare and index. Status
bits corresponding to count_enable, count
direction and sign are not affected.
B4 = 0: Nop.
1: Master reset. Resets MDR0, MDR1, STR, CNTR,
PR, OL, ISR and IMR
B5 = 0: Nop
1: Set sign bit
B6 = 0: Nop
1: Reset sign bit
B7 = 0: Nop.
1: Reset ISR bit for the selected axis
ISR:
The ISR is a trans-axis global register used to hold the
interrupt assertion status of all the axes. It is a 4-bit
read-only register with the following bit assignment.
ISR: B3 B2 B1 B0
B0
= 0: axis_0 interrupt cleared
= 1: axis_0 interrupt asserted
B1
= 0: axis_1 interrupt cleared
= 1: axis_1 interrupt asserted
B2
= 0: axis_2 interrupt cleared
= 1: axis_2 interrupt asserted
B3
= 0: axis_3 interrupt cleared
= 1: axis_3 interrupt asserted
An ISR bit gets set when the FLGa output of the
associated axis switches low. For this reason, in order
for the interrupt to be enabled for any axis, its associat-
ed FLGa output must be enabled. In addition, the
associated IMR bit must also be set for the interrupt to
be enabled.
An individual ISR bit can be cleared through its axis
relevant CMR register. The ISR is cleared upon
power-up.
A read of ISR produces a joint read of ISR and IMR
(interrupt mask register) with ISR occupying the upper
nibble and IMR occupying the lower nibble of the
databus.
