RA can be the GSR address or any BSR address.
Upon device power-up, all BSR lock-bits are locked. The Lock Status Upload command must be written to reflect the
actual lock-bit status.
A
0
is automatically complemented to load the second byte of data.
BCH/WCH must be at 00H for this product because of the 256-byte Page Buffer size
and
to avoid writing the Page Buffer
contents into more than one 256-byte segment within an array block. They are simply shown for Page Buffer expandability.
PA and PD (whose count is given in cycles 2 and 3) are supplied starting in the fourth cycle (not shown).
This command allows the user to swap between available page buffers (0 or 1).
These commands reconfigure RY/BY# output to one of two pulse modes, or they enable and disable the RY/BY# function.

DEVICE STATUS REGISTER
Each 28F016SA has three types of status registers:
the Compatible Status Register (CSR), the Global
Status Register (GSR) and the Block Status
Register (BSR). The CSR is identical to the
28F008SA status register. The GSR contains
queue and page buffer information about each
device. Each block within the device has a BSR
assigned to it. The BSR contains the block locking
status and other information specific to the block
being addressed.
