Resolution is 61.035 Hz if F(XOSC) = 32 MHz. Default value is
0xe4c000 = 915 MHz. Register values must be modified only
when device is in SLEEP or STAND-BY mode.

Imax = 45+5*OcpTrim [mA] if OcpTrim <= 15 (120 mA) /
rw
0x0B
Imax = -30+10*OcpTrim [mA] if 15 < OcpTrim <= 27 (130 to
240 mA)
Imax = 240mA for higher settings
Default Imax = 100mA
