16-bit 2-Phase Encoder Input Up/Down Counter/General Purpose Timer (TMENC10)
User’s Manual U16580EE3V1UD00
12.5.2 Operation in general-purpose timer mode
TMENC10 can perform the following operations in the general-purpose timer mode.
(1)
Interval operation
TMENC10 and CM100 always compare their values and the INTCM10 interrupt is generated upon
occurrence of a match. TMENC10 is cleared (0000H) at the count clock following the match.
Furthermore, when one more count clock is input, TMENC10 counts up to 0001H.
The interval time can be calculated by the following formula.
Interval time = (CM100 value + 1)
×
TMENC10 count clock rate
Caution:
Interval operation can be achieved by setting the ENMD bit of the TMC register to 1.
(2)
Free-running operation
TMENC10 performs full count operation from 0000H to FFFFH, and after the TM1OVF bit of the
STATUS10 register is set (1), TMENC10 is cleared and resumes counting.
The free-running cycle can be calculated by the following formula.
Free-running cycle = 65,536
×
TMENC10 count clock rate
Caution:
The free-running operation can be achieved by setting the ENMD bit of the TMC
register to 0.
(3)
Compare function
TMENC10 connects two compare register (CM100, CM101) channels and two capture/compare
register (CC100, CC101) channels.
When the TMENC10 count value and the set value of one of the compare registers match, a
match interrupt (INTCM10, INTCM11, INTCC10
Note
, INTCC11
Note
) is output. Particularly in the
case of an interval operation, TMENC10 is cleared upon generation of the INTCM10 interrupt.
Note:
This match interrupt is generated when CC100 and CC101 are set to the compare register
mode.
