spidriver.pdf instructions for SPI Flash should connect /HOLD

[dshadoff]

While using SPIFlash to read/write FeRAM device MR45V100A, I found that JEDEC ID was identified as {0x00, 0x00, 0x00} 90-99% of the time when the /HOLD line (pin 7 on SOP package) was left unconnected (as is demonstrated in the spidriver.pdf instruction file).

The datasheet for the device implied that both loose wires (/WP and /HOLD) should be brought to a logic "high", but I found that the JEDEC ID required just bringing /HOLD high.
