Need simple serial interface to ASICs for configuring registers and sending commands that allows for backpressure.
Existing Standards not a good fit
to an ASIC
Must allow allow for backpressure, so that ASIC can SPI: No backpressure. No way for ASIC to signal that it is done with a command or ready for new data.
Existing Standards not a good fit
SPI: No backpressure. Requires polling.
I2C: Backpressure possible through clock stretching, but complex protocol and implementation.

- Slave responds with Start Bit, Write bit, Command, Address and Data
- Master optionally raises saciSelL when done.
