Other Parts Discussed in Thread: UCD9222
Hello
I have to question using VCNTLID register.
I 'm using TMDSEVM6678L EVM board , in smartreflex the VCNTLID register can be modified by software for changing CVDD value in the UCD9222 or is only for seeing the register?
Best regards
Luis
Hi Luis,
VCNTLID register is provided for debug purposes only. It is defined in the PSC UG in Figure 3-2 where bits 21:16 are the only valid bits containing the 6-bit VID value. This register is not intended to be used for any type of software-based Smart Reflex control. The VCNTL pin output must be latched and used to control the voltage long before software is executing on the core or an external master such as I2C can access this internal register.
Refer below e2e thread,
Thank you.
