Interrupt Timing
The interrupt request and clearing cycles are shown in
Figure
HIGH) occurs sometime before Cycle 0. The interrupt
request is cleared by performing a single MPU write cycle
that sets RESETIRQ = 1 (bit number 11) in the CONTROL-
REG(15:0) register (BYTE address 0x19 or WORD address
0x0C).

The MPU interrupt request line (MPIRQ) remains active
HIGH until the RESETIRQ bit is set. The MPIRQ line
becomes inactive LOW two cycles after the completion of
the RESETIRQ write cycle (Cycle 4). For subsequent MPU
interrupt requests to be enabled, the RESETIRQ bit must be
reset and one of the three IRQ enable bits (DATABU-
FRDYIRQ, ERRORIRQ, and/or CFGDONEIRQ) in the
CONTROLREG register should be set.
