Macro
Figure 1-5. Interaction between Host and AFE79xx – Macro (Interrupt method)
To initiate Macro with large data transfer mode the following sequence is recommended.
1. Activate SPI page for Macro Memory
2. Write calibration data one byte at a time (SPI streaming mode)
3. Activate SPI page for Customer registers
4. Write Macro Operands (SPI streaming mode)
5. Write Macro opcode in trigger register
