i using msp430f5418 iar ew 5.10.

i trying output rtcclk signal msp's 29th pin frequency of 1hz.

when output signal coming through port.

but after re-writing rtc time, signal stopped.

i tried re-enable it, didn't worked.

can tell me reason is??

i using work-around code provided ti setting rtc time.

my rtc configuration is:

rtcctl01 |= rtchold;  rtcctl01 |= rtcmode + rtctev_0 + rtcrdyie + rtctevie;  p2dir |= bit4; p2sel |= bit4;  rtcctl23 = rtccalf1 | rtccal0; rtcctl01 &= ~(rtchold);

thank you,

harikrishnan

the rtc calibration depends on output of pre-scalar timer
