Direction Description
Output Opcode fold. An IT opcode has been folded in this cycle. PC advances past the
current (16-bit) opcode plus the IT instruction (16 bits). This is reflected in the
ETMIA.
Input Driven by the ETM (if connected). ETMFIFOFULL is asserted when the
ETM FIFO is full, and causes the processor to stall until the FIFO has drained,
so ensuring that no trace is lost.
Output Synchronization pulse from DWT.
