I'm having trouble with the RTC in the JM32. I wish to setup a 1 Hz periodic interrupt. I can do this only using 1 kHz LPO. This is not accurate enough. Neither the ERCLK or IRCLK work. On top of that the LPO works only if I use the default settings for bus clock (8 MHz in FEI mode). I wish to use a 24MHz bus from a 16MHz xtal. This works for for operations such as SPI, ADC, TPM, PWM etc. It's just that when running 24MHz bus by way of PEE mode the RTC will not work at all.
