CHAPTER 20 16-BIT RELOAD TIMER
20.6 Operations and Setting Procedure Example
■ Setting Procedure Example
Below is an example of procedure for setting the 16-bit reload timer.
● Initial setup
1. Set the interrupt level. (ILR*)
2. Set the reload value. (TMRHn/TMRLn)
3. Select the clock. (TMCSRHn:CSL[2:0])
4. Select the operating mode. (TMCSRHn:MOD[2:0])
5. Enable the output. (TMCSRLn:OUTE = 1)
6. Select the output level. (TMCSRLn:OUTL)
7. Select reload. (TMCSRLn:RELD)
8. Enable a count. (TMCSRLn:CNTE = 1)
9. Perform the software trigger. (TMCSRLn:TRG = 1)
10. Enable underflow interrupt. (TMCSRLn:INTE = 1).
*: For details of the interrupt level setting register (ILR), refer to "CHAPTER 5 INTERRUPTS" in this
hardware manual and "■ INTERRUPT SOURCE TABLE" in the device data sheet.
● Interrupt processing
1. Clear the underflow interrupt request flag. (TMCSRLn:UF=0)
2. Disable underflow interrupt. (TMCSRLn:INTE = 0)
3. Process any interrupt.
4. Enable underflow interrupt. (TMCSRLn:INTE = 1)
