Data Sheet
11.0 INTERRUPTS
11.1 Interrupt Priority and Polling Sequence
The device supports eight interrupt sources under a four level priority scheme. Table 11-1 summarizes the polling
sequence of the supported interrupts. Note that the SPI serial interface and the UART share the same interrupt
vector. (See Figure 11-1)
