Note: At VDD(TVDD) <5 V and residual carrier settings <50%, the accuracy of the modulation index may be low

in dependency of the antenna tuning impedance

8.6.2.1 Overshoot protection

The SLRC610 provides an overshoot protection for 100% ASK to avoid overshoots during a PCD

communication. Therefore two timers overshoot_t1 and overshoot_t2 can be used.

During the timer overshoot_t1 runs an amplitude defined by set_cw_amplitude bits is provided to the output

driver. Followed by an amplitude denoted by set_residual_carrier bits with the duration of overshoot_t2.
