7.4.13.3 Write Operation (No Post Increment)

To write a register in the extened register set:

Instruction Example: Set reg 0x0170 = 0C50

1. Write the value 0x001F (address function field = 00, DEVAD = 31) to register REGCR (0x0D).

 Write register 0x0D to value 0x001F

2. Write the desired register address to register ADDAR (0x0E).

 Write register 0x0E to value 0x0170

3. Write the value 0x401F (data, no post increment function field = 01, DEVAD = 31) to register REGCR.

 Write register 0x0D to value 0x401F
4. Write the content of the desired extended register set register to register ADDAR.

Write register 0x0E to value 0x0C50

Subsequent writes to register ADDAR (step 4) continue to rewrite the register selected by the value in the address register.

Note: Steps (1) and (2) can be skipped if the address register was previously configured.
