Peripheral: QSPI
Bug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range
0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for a
threshold level of 23-bytes, the actual value is 0x06 corresponding to a threshold level of 7-bytes.
Encountered on: STM32F723IE, STM32F746NG and STM32F767ZI
Comments: Checked the errata data sheets for the above processors and there is no mention of the bug.
Request: Please can anyone confirm that this is indeed an undocumented hardware bug.
