hi,
Is HREADY is used by the slave to notify the master that it is ready to receive or to indicate transfer is completed??
thanks in advance
HREADY signal is used for both cases:
to notify the master that slave is ready to transfer data (HREADY is high);
to notify the master that transfer is completed (HREADY is high).
When HREADY is low - the transfer is extended (wait state is added).
The Master also samples HRESP (from slave) for OKAY or ERROR transfers.
