To prevent electrical overstress, it is strongly recommended that you attach a series
resistor on the V
internal charge pump. For details, see

Regulator output voltage. These supplies are used to power the ISP1506 internal digital
and analog circuits, and must not be used to power external circuits.
For correct operation of the regulator, it is recommended that you connect REG3V3 and
REG1V8 to decoupling capacitors. For examples, see
XTAL1 is the crystal input, and XTAL2 is the crystal output. The allowed frequency on the
XTAL1 pin depends on the ISP1506 product version.
The ISP1506 requires external load capacitors to GND on each terminal of the crystal. For
details, see
If at any time the system wants to stop the clock on XTAL1, the link must first put the
ISP1506 into low-power mode. The clock on XTAL1 must be restarted before low-power
mode is exited.
This pin provides two optional functions. If neither function is used, this pin must be
