Memory Decoder Inputs
FIFO
Half-rate Clocking Mode
The eight memory map decoder inputs are connected to custom address decoders. The
address decoders divide the memory into regions of on-chip SRAM, on-chip ROM, and peripher-
als. The address decoders also optimize the ETM9 trace trigger.
Table 12-2.
A 45-byte FIFO is used to store data tracing. The FIFO is used to separate the pipeline status
from the trace packet. So, the FIFO can be used to buffer trace packets.
A FIFO overflow is detected by the embedded trace macrocell when the FIFO is full or when the
FIFO has less bytes than the user-programmed number.
The ETM9 is implemented in half-rate mode that allows both rising and falling edge data tracing
of the trace clock.
The half-rate mode is implemented to maintain the signal clock integrity of high speed systems
(up to 100 MHz).
Figure 12-5.
Care must be taken on the choice of the trace capture system as it needs to support half-rate
clock functionality.
