The Clock Selection Jumper, labeled JP-GCLK, on the CPLD Development/Program-
mer Board is a two-position jumper that allows the users to select which GCLK
dedicated input pin (either GCLK1 or GCLK2) of the ATF15xx should be connected to
the output of the 2 MHz oscillator. In addition, the jumper can be removed to allow an
external clock source to be connected to GCLK1 and/or GCLK2 of the ATF15xx. Figure
2-6 is the circuit diagram of the oscillator and selection jumper. Table 2-14 on page 2-10
shows the pin numbers for the GCLK1 and GCLK2 dedicated input pins of the ATF15xx
in all the different available package types.
