Proc Interface

The proc interface is only used to read the RTC status.

You can run the following command to execute the read process:

cat /proc/driver/rtc

The following code block shows an example of using the interface.

# cat /proc/driver/rtc
rtc time         : 00:06:19
rtc date         : 2001-02-01
alrm_time        : 00:00:10
alrm_date        : 2001-02-01
alarm_IRQ        : no
alrm_pending     : no
update IRQ enabled     : no 
periodic IRQ enabled   : no
periodic IRQ frequency : 1 
max user IRQ frequency : 64 
24hr             : yes
