Bit 8
Bit 10
IRQ Pin Format—Edge or Level Interrupt Selection.
If Bit 8 is set to 0, then an interrupt will cause a pulse
of one system clock to be generated on the IRQ pin.
If Bit 8 is set to 1, then an interrupt causes the IRQ
output to go LOW (logic 0). The IRQ output pin
will remain LOW until the SYSSTAT register is read.
If Bit 10 is set to 1, then the reverse Park transforma-
tion will be formed in 3/3 mode. For Forward
transformations, this bit must be set to 1.

Bit 0
A/D Conversion Completion Interrupt. This register
is set to 1 when the A/D conversion process has com-
pleted and ADC interrupts have been enabled in the
SYSCTRL register.
Bit 1
Interrupt Status. This register is set to 1 when the
Vector Transformation is completed and the Vector
Transformation completion interrupts have been
enabled.
Bit 4 This bit is set to 1 when the rotation results are valid.
Bit 11 If any interrupt source on the ADMC200 occurs, then
this bit is set to 1.
