Figure 5-11. SPI Interface Communication (Continuous Read Mode)
Note:
Special steps are needed to read the TRF796x IRQ status register (register address 0x0C) in SPI mode.
The status of the bits in this register is cleared after a dummy read. The following steps must be followed
when reading the “IRQ status register”.
1. Write in command 0x6C: read 'IRQ status' register in continuous mode (eight clocks).
2. Read out the data in register 0x0C (eight clocks).
3. Generate another eight clocks (as if reading the data in register 0x0D) but ignore the MISO data line.
This is shown in Figure 5-12.
