Is STM32H7Rxx/7Sxx affected by OTG_HS "transmit FIFO corrupted" erratum?

Other chips have the erratum "Transmit data FIFO is corrupted when a write sequence to the FIFO is interrupted with accesses to certain OTG_HS registers" (eg ES0392 2.25.2 for STM32H743). 

It isn't listed in the ES0596 rev5 errata for STM32H7Rxx/7Sxx - are those devices unaffected, or it just hasn't been listed there? Thanks.

Hi @mkj & welcome to ST Community
According to current errata sheet, this erratum is not applicable. Note that enabling DMA mode guarantees FIFO write sequence is not interrupted.
