Using the Extended SPI protocol the QIFP, QIEFP and the QIO-SPI Program/Erase
instructions, it is still possible to use the VPP additional power supply to speed up internal
operations. However, to enable this possibility it is necessary to set bit 3 of the Volatile
Enhanced Configuration Register to 0.
In this case the W/VPP/DQ2 pin is used as an I/O pin until the end of the instruction
sequence. After the last input data is shifted in, the application should apply VPP voltage to
W/VPP/DQ2 within 200 ms to speed up the internal operations. If the VPP voltage is not
applied within 200 ms the Program/Erase operations start with standard speed.
The default value of the VECR bit 3 is 1, and the VPP functionality for Quad I/O modify
instruction is disabled.
