8. Firmware Release Notes
Devices marked with firmware revision 02 (see "13. Device Marking Diagram" on page 34) have the firmware
revision registers set as 0x61 = 0x00; 0x62 = 0x02, and 0x63 = 0x51 (0.2.81).
The following is a known issue, which may be addressed with a future firmware revision:
8.1. I2C Address ACK
Issue
: Very rarely, the Si3452 may not ACK the I2C address byte.
Impact
: This is allowed in the I2C specification.
Workaround
: Retransmit the address byte if there is an ACK failure.
