Figure 15-2 Sample timing of “register read” with Mode 68
1. write register address (command write).
2. read register data (data read).
3. write register address (command write).
4. read register data (data read). Demonstrates how to access an odd numbered register 
using the low byte. Note that the high byte could also have been used by asserting 
EBU instead of EBL.
5. write register address (command write).
6. read register data (data read). Word accesses (16-bit) use the higher byte for the even 
register address and the lower byte for the odd register address.
