Section 25 Stream Interface (STIF)
(b) Receive Packet Length
The receive packet length can be selected from 188 and 192 bytes.
(c)
The size of the work area in external memory can be selected from among 0, 16, 32, and 48 bytes.
(d) Time Stamp Setting at Reception
The time stamp setting at reception can be selected from among reception with a fixed value
added, reception with a time stamp added, or reception without changes, according to the
STMP[1:0] bits in STIMDR.
• Reception with a fixed value added
• Reception with a time stamp added
• Reception without changes
(e)
During clock valid reception, the following interrupt sources are available.
• Receive packet count interrupt
• Short packet reception interrupt
• Long packet reception interrupt
• Receive FIFO overflow interrupt
• Time stamp counter overflow interrupt (only at reception with a time stamp added)

The value set in the time stamp counter is used as the fixed value (counting is not performed).
When the packet length is 188 bytes, a 4-byte fixed value is added to the front of the packet.
When the packet length is 192 bytes, the first four bytes of the packet are overwritten with the
fixed value.
When the packet length is 188 bytes, the time stamp counter value is added to the front of the
packet.
When the packet length is 192 bytes, data at the beginning of the packet is overwritten with the
time stamp counter value.
The time stamp counter starts counting from reception of the first packet.
Counting can be started from any desired value by setting the value before reception.
Writing to the counter during reception of a packet is prohibited.
This selection is possible only when the packet length is 192 bytes. In this case, the received
packet is transferred to memory without any changes.
