#161168 - it doesn't always work in the same way Responding to: ???'s previous message |
Some of the newer parts, e.g. two-clockers, or one-clockers, don't work out in exactly the samew way. Some offer data rates other than X1/12, and others leave the Mode 0 behavior totally undocumented (e.g. Maxim/Dallas).
Some MCU's follow the old Intel-specified timings while others do not. What's often really murky is the timing of the interrupt, or the TI and RI flags. Combine this with the notion that the system clock can be a multiple of the X1 oscillator input. I'd guess it's best to "read the fine print." RE |
