Description
RTC Channel 1 compare value.
Bit 31 to 16 represents seconds and bits 15 to 0 represents
subseconds of the compare value.
The compare value is compared against SEC.VALUE (15:0) and
SUBSEC.VALUE (31:16) values of the Real Time Clock register. A
Cannel 0 event is generated when
{SEC.VALUE(15:0),SUBSEC.VALUE (31:16)} is reaching or exciting
the compare value.
Writing to this register can trigger an immediate*) event in case the
new compare value matches a Real Time Clock value from 1 second
in the past up till current Real Time Clock value.
Example:
To generate a compare 5.5 seconds RTC start, set this value =
0x0005_8000
*) It can take up to 2 SCLK_LF clock cycles before event occurs due
to synchronization.
