and resulting another CIA read for more bits..

and toggles then to slower rise or a feedback from output, trying to linearize the RC curve current? Lemmethink

not sure but needs think: the opamp first gives an approximate value with faster rising speed, once near, it gives that delay value (resulting as CIA reads)
