I need ISP program of Winbond W25Q32BV chip (without removing it from board): as noted in Manual, the WP and HOLD pins must be pulled up to high with resistor: so its need be connected to VCC pin of the flash via the he pull-up resistor. Should it be one resistor between the Pin2 of ISP port connected via 2 lines: one line directly to VCC pin of the flash, and 2nd line to WP and HOLD pins of chip through the pull-up resistor? Or 2 resistors, one in each line,i.e. one between WP and VCC pin of chip and another between HOLD and VCC pin of chip? What is denomination of this pull-up resistor(s)?
