TIMER A.C. CHARACTERISTICS

Definitions :

Error = Indicated Time Value - Actual Time Value

tpsc = tCLKx Prescale Value

Internal Timer Mode

Single Interval Error (free running) (note 2)

± 100ns

Cumulative Internal Error

Error between Two Timer Reads

± (tpsc + 4tCLK)

Start Timer to Stop Timer Error

+ (2tCLK + 100ns) to - (tpsc + 6tCLK + 100ns)

Start Timer to Read Timer Error

+ 0 to – (tpsc + 6tCLK + 400ns)

Start Timer to Interrupt Request Error (note 3)

- 2tCLK to – (4tCLK + 800ns)

PULSE WIDTH MEASUREMENT MODE

Measurement Accuracy (note 1)

+ 2tCLK to – (tpsc + 4tCLK)

Minimum Pulse Width

4tCLK

EVENT COUNTER MODE

Minimum Active Time of TAI, TBI

4tCLK

Minimum Inactive Time of TAI, TBI

4tCLK

Not es :

1.Error may be cumulative if repetitively performed.

2.Error with respect to TOUT or INT if note 3 is true.

3.Assuming it is possible for the timer to make an inter-

rupt request immediately.
