0x1732 = 0x0F// Set Data Field Length = 16 bytes
0x1733 = 0x01// Enable Interrupt
0x1734 = 0x03// Set CMD Byte1 0x03 (code)
0x1735 = 0x04// Set CMD Byte2 0x04 (A23-A16)
0x1736 = 0x05// Set CMD Byte3 0x05 (A15-A8)
0x1737 = 0x06// Set CMD Byte4 0x06 (A7-A0)
0x1731 = 0x1B// Force 4 bytes TX (CMD), and 16 bytes RX (DATA)
6. Page Program (0x1734 = 02)
0x1730 = 0x83// Set DF_enb, CLK = CPU clock / 4
0x1732 = 0x0F// Set Data Field Length = 16 bytes
0x1734 = 0x02// Set CMD Byte1 0x02 (code)

0x173E = 0x00// Reset CPU write point to 0x00
0x173C = 0xD0// Write Data Byte 1 (first data byte)
0x173C = 0xDF// Write Data Byte 16 (last data byte)
0x1731 = 0x13// Force 4 bytes TX (CMD), and 16 bytes TX (DATA)
7. Release Power-down and Device ID (0x1734 = AB)
0x1730 = 0x84// Set DF_enb, CLK = CPU clock / 5
0x1732 = 0x00// Set Data Field Length = 1 bytes
0x1734 = 0xAB// Set CMD Byte1 0xAB (code)
0x1735 = 0x00// Set CMD Byte2 0x00 (dummy)
0x1736 = 0x00// Set CMD Byte3 0x00 (dummy)
0x1737 = 0x00// Set CMD Byte4 0x00 (dummy)
0x1731 = 0x1B// Force 4 bytes TX (CMD), and 1 byte RX (DATA)
8. Manufacturer-Device ID(0x1734 = 90)
0x1730 = 0x85// Set DF_enb, CLK = CPU clock / 6
0x1732 = 0x01// Set Data Field Length = 2 bytes
0x1734 = 0x90// Set CMD Byte1 0x90 (code)
0x1735 = 0x00// Set CMD Byte2 0x00 (dummy)
0x1736 = 0x00// Set CMD Byte3 0x00 (dummy)
0x1737 = 0x00// Set CMD Byte4 0x00 (00h)
0x1731 = 0x1B// Force 4 bytes TX (CMD), and 2 bytes RX (DATA)
9. JEDECID(0x1734 = 9F)
0x1730 = 0x85// Set DF_enb, CLK = CPU clock / 6
0x1732 = 0x02// Set Data Field Length = 3 bytes
0x1734 = 0x9F// Set CMD Byte1 0x9F (code)
0x1731 = 0x18// Force 1 bytes TX (CMD), and 3 bytes RX (DATA)
