280 // in order to get the correct address and payload.
281 //
282 // cmdfifo_depth (SCK) is a registered signal. So, it becomes notempty after
283 // 8th beat of the SCK. The CSb as a clock latches the signal to be != 0,
284 // then sys_cmdfifo_set signal let SYS_CLK latch the notempty signal.

295 // the logic pushes one more to the FIFO, it does not generate event
296 // signal.

280 // in order to get the correct address and payload.
281 //
282 // cmdfifo_depth (SCK) is a registered signal. So, it becomes notempty after
283 // 8th beat of the SCK. The CSb as a clock latches the signal to be != 0,
284 // then sys_cmdfifo_set signal let SYS_CLK latch the notempty signal.

290 // high. The edge detector could not catch the change.
291 //

295 // the logic pushes one more to the FIFO, it does not generate event
296 // signal.
