QE128, real-time counter, and ERCLK

    The QE128 is running from an external 32kHz crystal with a bus speed of 1.245MHz.  I can't seem to get the real-time counter to work if the ERCLK is selected as the source.  These are the register settings:


ICSC1 = %10000000

ICSC2 = %11011111

ICSSC = %00100000


RTCSC = %10110001


    The RTC interrupt is called as expected if the LPO is selected or the IRCLK is enabled and selected as the source.


    What am I missing?
