MDataLast signal behaviour in OCP protocol version 2.2

Hi,

MDatalast signal is asserted by master to inform the slave that master is sending the last data in burst(MBurstLength > 1).
Do we have to assert MDataLast signal when master sends packet with MBurstLength =1?

Same doubt i have for MReqLast signal also?
Can anyone please help to understand this signal behaviour.
