25.3.10 External Memory Configuration for Stream Data Transmission/Reception
Figure 25.2 shows the external memory data configuration when transmitting or receiving stream
data (in the case of a 16-byte work area). The work area size can be selected from among 0, 16,
32, and 48 bytes by the WORK bits in STIMDR. If addition of time stamp or fixed value is
selected and the data length is 192 bytes, the first four bytes of the received data will be
overwritten.
