Notes:
1. 12-24ms latency occurs on each command issued. The effect of this latency is reduced by transferring
large amounts of data with a single block read command. Maximum read throughput is achieved by
reading >64K bytes of data from a FIFO type register on an M-module using the Block Read
command. Host software may vary and can limit the maximum throughput.
2. The maximum number of bytes that can be written in a single block write command is 1024.
3. Ethernet is a non-deterministic communications interface. Realized throughput may be significantly
degraded by network activity or other factors that may affect network performance.
4. TLVL and TIMP refer to register bits in the Reset & Trigger Control register. Refer to section 4.3.5.
