CLKSource—Clock Source Register
Bit 7: CLKtoRTS
Set the CLKtoRTS bit to 1 to route the baud-rate generator (16x baud rate) output clock to RTS/CLKOUT. The clock
frequency is a factor of 16x, 8x, or 4x of the baud rate, depending on the BRGConfig[5:4] settings.
Bits 6 and 5: No Function
Bit 4: ClockEn
Set the ClockEn bit high to enable an external clocking (crystal or clock generator at XIN). Set the ClockEn bit to 0 to
disable clocking.
Bit 3: PLLBypass
Set the PLLBypass bit high to enable bypassing the internal PLL and predivider.
Bit 2: PLLEn
Set the PLLEn bit high to enable the internal PLL. If PLLEn is set low, the internal PLL is disabled.
Bit 1: CrystalEn
Set the CrystalEn bit high to enable the crystal oscillator. When using an external clock source at XIN, CrystalEn must
be set low.
Bit 0: No Function
Always keep Bit 0 at logic 0.
RevID—Revision Identification Register
Bit 7–0: Bit[7:0]
The RevID register indicates the revision number of the MAX3107 silicon, starting with 0xA1. This can be used during
software development.
