Advisory CLB: Back-to-Back PUSH or PULL Instructions With More Than One Active High-
Level Controller (HLC) Channel is Not Supported
Revisions Affected
0, A, B, C
Details This issue only affects HLC operations if using back-to-back PUSH or PULL instructions
with more than one active HLC channel.
Workarounds Re-order the HLC instructions so that every PUSH instruction is followed by a non-PUSH
instruction. The same applies for the PULL instruction. If only one HLC channel is active,
this issue does not occur.
Advisory USB: USB DMA Event Triggers are not Supported
Revisions Affected
0, A, B, C
Details The USB module generates inadvertent extra DMA requests, causing the FIFO to
overflow (on IN endpoints) or underflow (on OUT endpoints). This causes invalid IN DATA
packets (larger than the maximum packet size) and duplicate receive data.
Workarounds None
