STM32WL55 Erratum Clairification

In the SubGHz_Phy_PingPong example for the Nucleo-WL55JC2 there two register reads and writes to addresses that are not documented in reference manual.

• 0x0889
• 0x0736

The reference manual (RM0453 Rev 1) and erratum (ES0500 - Rev 1) for the STM32WL55 series both do not mention these registers.

However, the semtech SX1268 datasheet (Rev 1.1 June 2019) does mention these registers as part of an erratum (modulation quality with 500 kHz LoRa bandwidth and Optimizing the inverted IQ operation).

Question: Does the sub-GHz radio in the STM32WL55 have the same erratum as the SX1268 for these registers?
