8-bit MicrocontrollersのトピックCan't Use the Internal Ref OSC in STOP Mode (QG8)? https://community.nxp.com/t5/8-bit-Microcontrollers/Can-t-Use-the-Internal-Ref-OSC-in-STOP-Mode-QG8/m-p/130361#M2427 <HTML><HEAD></HEAD><BODY><SPAN>In the 9(S)08QG8, I see where I can keep the Internal Reference Oscillator running when in STOP mode. As I read this I was thinking, "good, I can use that for my RTI timebase when in STOP mode". Then I see that the RTI can only use an EXTERNAL clock or the 1KHz internal oscillator (with an accuracy that I cannot find in the datasheet). Why is there an option to keep the Internal Ref Osc running in STOP3 if it cannot be used as the RTI timebase? Furthermore, I can't see that it's used anywhere in STOP mode. Is it to be left running just to keep the engine warm?</SPAN><BR /><BR /><SPAN>My objective is to have an RTI with fairly good accuracy, and no crystal. (And pulling only a few microamps.) Any suggestions would be appreciated.</SPAN></BODY></HTML> Tue, 28 Mar 2006 22:18:16 GMT Wings 2006-03-28T22:18:16Z Can't Use the Internal Ref OSC in STOP Mode (QG8)? https://community.nxp.com/t5/8-bit-Microcontrollers/Can-t-Use-the-Internal-Ref-OSC-in-STOP-Mode-QG8/m-p/130361#M2427 <HTML><HEAD></HEAD><BODY><SPAN>In the 9(S)08QG8, I see where I can keep the Internal Reference Oscillator running when in STOP mode.
