RX62N Group, RX621 Group 4. Library Reference
Remarks
•
Interrupts are enabled automatically if a callback function is specified.
Please see the notes on callback function usage in §6.
•
If an external trigger is used, the low-level pulse width must be at least 1.5 PCLK cycles.
•
This function brings the converter unit out of the power-down state.
•
A callback function is executed by the interrupt processing function. This means that no other
interrupt can be processed until the callback function has completed.
•
-A or –B pin selection is not available on the 85-pin package.
•
Function R_CGC_Set must be called before any use of this function.
•
Allow 10ms to elapse from the completion of this function to the start of the first conversion.
•
For more details of the MTU or TMR trigger options, please refer to the RX62N hardware
manual.
