, 14:49, 22 July 2008→FPGA/EEPROM Pull-up Resistors: changed to say they aren't necessary
Line 26:
Line 26:
As shown in the [[:Image:SiPM FPGA and EEPROM Connections.gif |connection diagram]], 4.7kΩ pull-up resistors are necessary to pull up the DONE, INIT_B and PROG_B pins to VCCO.+

−Despite being shown in the [[:Image:SiPM FPGA and EEPROM Connections.gif |connection diagram]], 4.7kΩ pull-up resistors are not necessary to pull up the DONE, INIT_B and PROG_B pins to VCCO, since we will be enabling internal pull-ups using the PUDC_B pin.
