Hi team,
Could you give me comment on following customer question?
Q1. What is the default value on CONFIG1?
The customer verified the default value on CONFIG1 after powering on the device, but they could read 0x48, not 0x4C as expected. Is 0x48 default value? In the same way, they could read 0x4C in TPS65218D0 device. It's not sure why the default value seems to be different. Could you give me advice on what may happen in this case?
Best regards,
Takeshi Sasaki
Hi Takeshi-san,
Thank you for reaching out via E2E. The TPS65218D0 is a newer device with upgraded functionality compared to the TPS65218, but some of the register defaults are different between the two devices.
Referring to both product's datasheets the CONFIG1 default value is different. CONFIG1 default is 0x48 on the TPS65218 (TPS65218 Power Management for ARM® Cortex
-A8/A9 SOCs and FPGA datasheet (Rev. E) (ti.com) page 57) and CONFIG1 default is 0x4C on the TPS65218D0 (TPS65218D0 Power Management for ARM Cortex-A8/A9 SOCs and FPGAs datasheet (Rev. B) (ti.com) page 63).
Based on this the default value the customer is observing is correct for both devices.
Best Regards,
Garrett
