Hello Support team,
My customer is evaluating TPS65987D on their board. When they read any RO address, they can read properly. However, when they read RW address, they can’t read anything. Could you confirm why they can’t read RW address bit?
Register Number |
Read/Write |
Byte Count |
Data Byte |
0x00 |
RO |
1 |
41 43 45 32 |
0x70 |
RW |
0 |
0 |
Even if they send write command, then, they read the RW address, they can’t read.
Thanks,
Koji Ikeda
Hi,
Sharing the details of the issue as it would be helpful to others.
Only a limited set of RW register are accessible in PTCH mode. In this case, PD controller was in PTCH mode and that caused I2C interface to return Zeros to RW register reads.
Thanks
