Interrupt Status (ISR)
Read/Write
The individual bits of this register may be written to force an interrupt on
the corresponding bit. Clearing these bits does not clear the interrupt,
unless it was originally set in this register.

SCSI Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the SCSI block. The bit goes to 0 when the interrupt is
cleared from the SCSI block.
Two-Wire Interface 1 Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the two-wire serial port_1 block. The bit goes to 0 when
the interrupt is cleared from the two-wire serial port_1
block.
Two-Wire Interface 0 Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the two-wire serial port_0 block. The bit goes to 0 when
the interrupt is cleared from the two-wire serial port_0
block.
DMA Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the DMA block. The bit goes to 0 when the interrupt is
cleared from the DMA block.
Timer 2 Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the timer2 block. The bit goes to 0 when the interrupt is
cleared from the Timer2 block.
Timer 1 Interrupt (read only)
A value of 1 in this bit indicates an interrupt pending from
the timer1 block. The bit goes to 0 when the interrupt is
cleared from the Timer1 block.
