The X25F128 also features two additional inputs that provide the end user with added flexibility. By asserting the HOLD input, the X25F128 will ignore transitions on its inputs, thus allowing the host to service higher priority interrupts. The PP input can be used as a hardwire input to the X25F128 disabling all program attempts to the status register, thus providing a mechanism for limiting end user capability of altering 0, 1/4, 1/2, or all of the memory. |
