How do you connect the buspirate to the chip and what is the chip's
form factor (e.g. soic8)? The datasheet mentions SOP/WSON/PDIP.

This is how I connect my buspirate to a MX25L1605A soic8 chip:

CS# (CS)						[1	8]	VCC (bridge with buspirate pin 3+7)
SO (MISO)					[2	7]	HOLD # (+3V3)
WP# (bridge with buspirate pin 7+8)	[3	6]	SCLK (CLK)
GND (GND)					[4	5]	SI (MOSI)

It's not necessary to change modes (no need to change from HiZ to SPI).
