Programming the Device
PRELIMINARY
Masking Interrupts
If an interrupt is not masked (enabled) the IREQ pin will be active if one of the status bits
in the interrupt status register is set. The mask bit prevents that the IREQ pin will be
active if the status bit is set. The mask bits for the error status registers or general
purpose interrupt register disable the interrupt indication for the interrupt status register.
Only the interrupt status register can set the IREQ pin if the bit is not masked.

16-bit µP Access Interrupt Structure
In opposite to the 8-bit µP access there is only one bit (ER1) to indicate a change in the
16-bit Interrupt Error Status Register 1.
