SPI Operation Summary
To Write:
9. Bring CS low.
10.Chip Address (7-bits) - This should match the RF3000 chip address of 0100000
2
.
11.Read/Write-bit = '0'
12.Auto-Increment-bit - Value of '1' enables auto-increment
13.Memory Address Pointer (MAP) (7-bits) - This is the address of the register to be written to, MSB first.
14.Register Data (8-bits) - MSB First
15.Repeat step 6 if Auto-Increment or bring CS HIGH to end operation.
To Read:
1. Bring CS low.
2. Chip Address (7-bits) - This should match the RF3000 chip address of 0100000
2
.
3. Read/Write-bit = '0'
4. Auto-Increment-bit - Value of '1' enables auto-increment
5. Memory Address Pointer (MAP) (7-bits) - This is the address of the register to be written to, MSB first.
6. Bring CS high.
7. Bring CS low.
8. Chip Address (same as step 2) - MSB First
9. Read/Write-bit = '1'
10. RF3000 will output 8-bit register value, MSB First, and Increment MAP, if Auto increment enabled.
11. Repeat step 10 for polling or Auto-Increment or bring CS high to end operation.
