the AMBA AHB bus master interface to start a burst with only 1 data transfer without the HSEL signal

Hi all.

A burst is a sequence of multiple data transfers (e.g., 4, 8, or 16 beats). The AMBA AHB specification requires bursts to be continuous. The HSEL (Slave Select) signal is generated by the decoder(AHB AMBA bus) based on the master’s address. It informs the slave that it is the target of the transfer. I saw AMBA AHB bus master IF started a burst with only 1 data transfer without the HSEL signal. The slave will ignore the transfer if HSEL is inactive. But I want to know this the normal operation of AMAB AHB bus and it can be problematic in AHB protocol.

Thanks in advance.
