MAX14830
Quad Serial UART with 128-Word FIFOs
and Internal Oscillator
38
STSInt—Status Interrupt Register
Bits 7, 6: No Function
Bit 5: ClockReady
The ClockReady bit is set high when the clock, the divider, and PLL have settled and the MAX14830 is ready for data
communication. The ClockReady bit only works with the internal oscillator or 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].
Bit 4: No Function
Bits 3–0: GPI[n]Int
Each UART has four individually assigned GPIO outputs as follows: UART0: GPIO0–GPIO3, UART1: GPIO4–GPIO7,
UART2: GPIO8–GPIO11, UART3: GPIO12–GPIO15. For example, for UART0: Bit 0 is GPI0Int, Bit 1 is GPI1Int, Bit 2 is
GPI2Int, and Bit 3 is GPI3Int. See Table 1.
The GPI[n]Int interrupts are set high when a change of logic state occurs on the associated GPIO_ input. GPI[n]Int is
cleared upon reading. These interrupts can be selectively routed to the ISR[2] interrupt bit through the STSIntEn[3:0].
