www.ti.com Instruction Set
angle_count Specifies when the counter is incremented. A value of ON causes the
counter value to be incremented only if the new angle flag is set
(NAF_global = 1). A value of OFF increments the counter each time
the CNT instruction is executed.
Default value for this field is OFF.
comp When set to EQ the counter is reset, when it is equal to the maximum
count.
When set to GE the counter is reset, when it is greater or equal to the
maximum count.
Default: GE.
irq ON generates an interrupt when the counter overflows to zero. The
interrupt is not generated until the data field is reset to zero. If irq is
set to OFF, no interrupt is generated.
Default: OFF.
max Specifies the 25-bit integer value that defines the maximum count
value allowed in the data field. When the count in the data field is
equal to max, the data field is reset to 0 and the Z system flag is set
to 1.
data Specifies the 25-bit integer value serving as a counter.
Default: 0.
