8.4.20 Write Operation (Post Increment)

To write a register in the extended register set with post increment:

  1. Write the value 0x1F (address function field = 00, DEVAD = '11111') to register REGCR.
  2. Write the desired register address to register ADDAR.
  3. Write the value 0x801F (data, post increment function field = 10, DEVAD = '11111') or the value 0xC01F (data, post increment on writes function field = 11, DEVAD = '11111') to register REGCR.
  4. Write the content of the desired extended register set to register ADDAR.

Subsequent writes to register ADDAR (step 4) write the next higher addressed data register selected by the value of the address register; the address register is incremented after each access.
