3.2.3 Data Burst Transfers
The data burst timing is used to support the full data rate of 148.5 MByte/s.
PDATA[35..0] and PARITY are updated with each rising edge of WRCLK.

3.2.4 Single Word Transfers
Single Word Transfers are used to support lower data rates. Every time a new data word is received
the WRCLK signal generates one clock pulse.
