51 / 85 page 51 ADVANCED INFORMATION REV. 0.00, FEB. 17, 2015 MX25R512F P/N: PM2189 9-24. 4 x I/O Page Program (4PP) The Quad Page Program (4PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit and Quad Enable (QE) bit must be set to "1" before sending the Quad Page Program (4PP). The Quad Page Programming takes four pins: SIO0, SIO1, SIO2, and SIO3 as address and data input, which can improve programmer performance and the effectiveness of application. The 4PP operation frequency supports as fast as f4PP. The other function descriptions are as same as standard page program. The sequence of issuing 4PP instruction is: CS# goes low→ sending 4PP instruction code→ 3-byte address on SIO[3:0]→ at least 1-byte on data on SIO[3:0]→CS# goes high.
