To insure inadvertent access to the PSRAM registers during asynchronous operation, the system
must avoid the below two command sequences when accessing the main memory array. On the 3rd
cycle of the below command sequences the write to the main memory may be blocked and the
software register access mode may be entered. To avoid such possibility, the system should avoid
the below command sequences unless it is intending to access the registers through the software
method.
