Example:

CoderRate = 0x05 (~52.97kHz)

For I

•CODE1 standard mode the interval should be 8.458ms

->TimeSlotPeriod = CoderRate * interval = 52.97kHz * 8.458ms –1 = 447 (447 = 0x1BF)

Note: The MSB of the TimeSlotPeriod is in the MFOUTSelect register.

Note: It is strictly recommended that bit TxCRCEn is set to 0 before the Quit-Frame is sent. If the TxCRCEn

is not set to 0 a CRC value is calculated and sent with the Quit-Frame.

To calculate the Quit value a CRC8 algorithm has to be used.

Usage of the Timer Unit

9.3.1

TIME-OUT- AND WATCH-DOG-COUNTER

Having started the timer by setting TReloadValue the timer unit decrements the TimerValue Register

beginning with a certain start event. If a certain stop event occurs e.g. a bit is received from the card, the

timer unit stops (no interrupt is generated).

On the other hand, if no stop event occurs, e.g. the card does not answer in the expected time, the timer unit

decrements down to zero and generates a timer interrupt request. This signals the µ-Processor that the

expected event has not occurred in the given time TTimer.
