We are having issues with LD remaining high consistently at cold operating temperature. I believe we are running all defaults in the LKD/CSP register 20.9
I see there is an option to use a ring oscillator for LD with a 3 bit callout for one shot duration. Bits 16:14 active only if bit 13 is high.
I don’t see any timing reference of what the relative durations are for this type of LD. Is there a nsec value for each bit in this 3 bit word?
Does bit 19 also need to be set to 1 for this to work?
How to choose the adjust the One-Shot Duration when using the Digital Ring Oscillator One-Shot:
Register 7 Bits[18:17] control the frequency of the Ring Oscillator.
Register 7 Bits[16:14] control the pulse width which is comprised of a number of cycles of the
Ring Oscillator (ranging from 0.5 to 64 cycles of the Ring Oscillator).
But nowhere do I see an even approximate value of the ring oscillator frequency.
