The Global Interrupt Source Registers
The XR16V698 has a global interrupt source register set that consists of 4 consecutive registers [INT0, INT1,
INT2 and INT3]. The four registers are in the device configuration register address space.
All four registers default to logic zero (as indicated in square braces) for no interrupt pending. All 8 channel
interrupts are enabled or disabled in each channel’s IER register. INT0 shows individual status for each
channel while INT1, INT2 and INT3 show the details of the source of each channel’s interrupt with its unique 3-
bit encoding. Figure 13 shows the 4 interrupt registers in sequence for clarity. The 16-bit timer and sleep
wake-up interrupts are masked in the device configuration registers, TIMERCNTL and SLEEP. An interrupt is
generated (if enabled) by the 698 when awakened from sleep if all 8 channels were placed in the sleep mode
previously.
