Posted on March 14, 2013 at 15:30Is OTG_FS_DAINT register ReadOnly or Read/Write ?
According to the reference it is RO but in USB Demo source code provided by ST I see many writes to this register of 0xFFFFFFFF in attempt to clear pending INT bits.
Who is wrong FW or Manual?
I think FW as manual clearly states ''Bits in this register are set and cleared when the
application sets and clears bits in the corresponding Device Endpoint-x interrupt register
(OTG_FS_DIEPINTx/OTG_FS_DOEPINTx).''.
