Description

IRTC

Properties

Properties not inherited from the base binding file.

Name

Type

Details

clock-src

int

The input clock select for IRTC.
0 <- 16.384 kHz
1 <- 32.768 kHz

Legal values: 0, 1

output-clk-en

int

Enable clock as an output for other peripherals to use.
0 <- No clock output
1 <- Fine 1Hz
2 <- Buffered Oscillator Clock
3 <- Coarse 1Hz
Default value ensures the output clock is turned off.
This is the reset value.

Legal values: 0, 1, 2, 3

share-counter

boolean

This secondary IRTC instance shares the data and time counters of the primary IRTC instance.
This means the code cannot set the data and time counters, but can only read them.

clock-frequency

int

Clock frequency information for RTC operation

prescaler

int

RTC frequency equals clock-frequency divided by the prescaler value

alarms-count

int

Number of alarms supported by RTC device. The number of
alarms defaults to 0, which indicates that the RTC has
no alarms.
