SPI/I2C UART with 128-Word FIFOs
Bits 7 and 4: No Function
Bit 6: SleepIntEn
Set the SleepIntEn bit high to route the SleepInt status bit to the ISR[2]: STSInt. If set low, the STSIntEn masks the ISR[2]
bit from SleepInt.
Bit 5: ClkRdyIntEn
Set the ClkRdyIntEn bit high to route the ClockReady status bit to the ISR[2]: STSInt bit. If set low, the ClkRdyIntEn
masks the ISR[2] bit from the ClockReady status.
Bits 3–0: GPI[3:0]IntEn
The GPI[3:0]IntEn bits that are set high route the associated STSInt[3:0]: GPI[3:0]Int bits to the ISR[2] interrupt. GPI[3:0]
IntEn bits that are set low, mask the ISR[2] interrupt from the associated GPI[3:0]Int bit.
Bits 7 and 4: No Function
Bit 6: SleepInt
The SleepInt bit is set when the MAX3107 enters sleep mode. The SleepInt bit is cleared when the MAX3107 exits sleep
mode. This status bit is cleared when the clock is disabled and cannot be cleared upon reading. The SleepInt bit can
generate an ISR[2]: STSInt interrupt, if enabled through STSIntEn[6].
Bit 5: ClockReady
The ClockReady bit is set high when the clock, the divider, and the PLL have settled, and the MAX3107 is ready for
data communication. The ClockReady bit only works with the crystal oscillator. It does not work with external clocking
through XIN.
The ClockReady status bit is cleared when the clock is disabled and is not cleared upon read. This bit can generate
an ISR[2]: STSInt interrupt, if enabled through STSIntEn[5].
Bits 3–0: GPI[3:0]Int
The GPI[3:0]Int interrupts are set high when a change of logic state occurs on the associated GPIO_ input. GPI[3:0]Int
is cleared upon reading. These interrupts can be selectively routed to the ISR[2] interrupt bit through the STSIntEn[3:0].
