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)

Cumulative Internal Error

Error between Two Timer Reads

Start Timer to Stop Timer Error

Start Timer to Read Timer Error

Start Timer to Interrupt Request Error (note 3)

PULSE WIDTH MEASUREMENT MODE

Measurement Accuracy (note 1)

Minimum Pulse Width

EVENT COUNTER MODE

Minimum Active Time of TAI, TBI

Notes :

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.
