This anomaly applies to Engineering A, build code QFAA-Axx.
Symptoms
When a MATCH event is generated, DMA.RX.AMOUNT does not reflect the position of the character in memory.
Conditions
TWIM, SPI, or UART is used in RX mode with match candidates set up and match filter enabled.
Consequences
DMA.RX.AMOUNT cannot be used as a reliable offset with DMA.RX.PTR to find the matching character in memory.
