Remarks
•
Function R_CGC_Set must be called before any use of this function.
•
This function is an alternative to R_TMR_CreateChannel and R_TMR_CreateUnit.
•
This function stops the timer on completion, so no other TMR function calls are required.
•
User needs to ensure no higher priority modules using the same pins as required by this
function.
•
If a callback function is specified, this function will enable the relevant interrupt.
Please see the notes on callback function usage in §6.
•
If no callback function is specified, this function waits for the CMIB flag to indicate that the
one-shot time delay is complete. If the timer’s control registers are directly modified by the user,
this function may lock up.
•
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.
•
The timer period limits depend on the peripheral module clock, PCLK.
