nRF24LE1 Preliminary Product Specification
9.4.1
The IEN0 register is responsible for global interrupt system enabling/disabling and also Timer 0, 1 and 2,
Port 0 and Serial Port individual interrupts enabling/disabling.
9.4.2
The IEN1 register is responsible for RF, SPI and Timer 2 interrupts.
2-Wire Master SPI and Slave SPI share the same interrupt line.
9.4.3
The 14 interrupt sources are grouped into six priority groups. For each of the groups, one of four priority
levels can be selected. They can be selected by setting appropriate values in IP0 and IP1 registers.
