/**
 * @xcload: Selects the amount of additional on-chip capacitance to
 *          be connected between XTAL1 and gnd and between XTAL2 and
 *          GND. One half of the capacitance value shown here is the
 *          additional load capacitance presented to the xtal. The
 *          minimum step size is 0.277 pF. Recommended value is 0x28
 *          but it will be layout dependent. Range is 0–0x3F i.e.
 *          (0–16.33 pF)
 * @ctsien: enable CTSINT(interrupt request when CTS condition
 *          arises) when set
 * @intsel: when set A1 pin becomes the interrupt pin; otherwise,
 *          INTB is the interrupt pin
 * @func:   selects the boot function of the device. I.e.
 *          SI476X_BOOTLOADER  - Boot loader
 *          SI476X_FM_RECEIVER - FM receiver
 *          SI476X_AM_RECEIVER - AM receiver
 *          SI476X_WB_RECEIVER - Weatherband receiver
 * @freq:   oscillator's crystal frequency:
 *          SI476X_XTAL_37P209375_MHZ - 37.209375 Mhz
 *          SI476X_XTAL_36P4_MHZ      - 36.4 Mhz
