A6 06/16/2025 8.56 PROGRAM ASP OPERATION (PGASP, 2Fh) Before the Program ASP (PGASP) command can be accepted by the device, a Write Enable (WREN) command must be issued. After the WREN command has been decoded, the device will set the Write Enable Latch (WEL) in the Status Register to enable any write operations. The PGASP command is entered by driving CE# low, followed by the instruction code and two data bytes, least significant byte first, most significant bit of each byte first. The ASP Register is two data bytes in length. The PGASP command affects the Write In Progress (WIP) bit in the same manner as any other programming operation. CE# input must be driven high after the sixteenth bit of data has been latched in. If not, the PGASP command is not executed. As soon as CE# is driven high, the PGASP operation is initiated. While the PGASP operation is in progress, the Status Register may be read to check the value of WIP bit. The WIP bit is “1” during the PGASP operation, and is “0” when it is completed. When the PGASP operation is completed, the WEL is set to “0”.
