PDM receive can lock-up in ISR mode when ma_frame_rx is not called isochronously after first transfer #230
Description
Even when AssertOnDroppedBlock(true) is set, in certain circumstances (continuous transfer at frame rate followed by delay of greater than 2x the frame period) PDM Rx may lock up in ISR mode.
I think the credit scheme (in ASM) needs refining further and a test to be written for this.
