BQ34110: checksum reading is inconsistent

Part Number: BQ34110

What would be the reason for corruption of the checksum reading after repeated access?

Here is a sequence of a successful read (0xD35B) followed by a corrupted one (0x5B00)

10.897322920000001,108,0xAA,0x3E,Write,ACK
10.897531980000000,108,0xAA,0x05,Write,ACK
10.897718660000001,108,0xAA,0x00,Write,ACK
10.900524539999999,109,0xAA,0x40,Write,ACK
10.901775819999999,110,0xAB,0xD3,Read,ACK
10.901977020000000,110,0xAB,0x5B,Read,NAK

11.200295940000000,111,0xAA,0x05,Write,ACK
11.200482600000001,111,0xAA,0x00,Write,ACK
11.203105539999999,112,0xAA,0x40,Write,ACK
11.204484860000001,113,0xAB,0x5B,Read,ACK
11.204686040000000,113,0xAB,0x00,Read,NAK

Increasing the interval between reads makes the problem worse, but out of hundreds of attempts, one or two are successful.

Any reason for that?

Thank you!
