Ignore command [DESL]:
When this command is set (
CS
is High), the SDRAM ignore command input at
the clock. However, the internal status is held.
No operation [NOP]:
This command is not an execution command. However, the internal operations
continue.
Burst stop in full-page [BST]:
This command stops a full-page burst operation (burst length = full-page
(256; HM5264165F, 512; HM5264805F, 1024; HM5264405F)), and is illegal otherwise. When data
input/output is completed for a full page of data, it automatically returns to the start address, and input/output
is performed repeatedly.
