UART break condition with M16C/64
Hi there,after solving various debugging-related problems during the last days, I now got stuckwith generating a UART0 async break-condition.The approach of halving the baud rate and sending one byte does not seem to work: u0brg = (unsigned char)( ( (12000000UL / 16) / 28800UL) - 1); while (!ti_u0c1 ...

Debug of M16C/64 Group MCU: why it slow down when using break
... with the low-speed on-chip oscillator*, the flash memory reprogramming takes longer and the E8a response rate diminishes. You can prevent the flash memory reprogramming by setting the event break at a higher priority. *M16C/64 Group MCUs operate on the low-speed on-chip oscillator after reset.

(M16C/5X,M16C/63,M16C/64,M16C/65) What happens to count source when CPU clock is changed?
For peripheral functions supplied by peripheral function clock f1, the on-chip oscillator clock becomes the count source of those peripheral functions. For peripheral functions supplied by any of peripheral clocks fOCO-S, fOCO-F, FOCO40M, fC32, or fC, their count sources will be unchanged even if the CPU clock ...

(M16C Family products other than the M32C/80 Series, and the M16C/80 Series) Priority level is "0" + Request bit is "1": Priority level to "7"?
The interrupt will be accepted. Then, the interrupt request bit will be cleared. However, if you use the MOV instruction to change the interrupt priority level, the interrupt request bit may be cleared to "0". The interrupt will not be accepted when the interrupt request bit is cleared at this ...
