NH are peripheral bus latencies (n
tHCLK); these are internal DSP latencies related to the number of peripherals attempting to access DSP memory at
the same time.
2Measurement is for the second, third, or fourth byte of a host read transaction. The quantity of bytes to complete a host read transaction is dependent on
the data bus size (8 or 16 bits) and the data type (16 or 24 bits).
