Product data sheet COMPANY PUBLIC Rev. 3.0 — 7 October 2016 240930 63 of 149 NXP Semiconductors PN5180 High-performance multi-protocol full NFC Forum-compliant frontend 11.8.3.3 TX Wait Tx_wait can be used for 2 different purposes: On the one hand, it can be used to prevent start of transmission before a certain period has expired - even if thePN5180 has already finished data processing and set the START_SEND bit. This behavior is intended for the reader mode to guarantee the PICC to PCD frame delay time (FDT). On the other hand, the tx_wait time can be used to start the transmission at an exactly defined time. For this purpose, data to be sent must be available and the START_SEND flag has to be set by FW before the period expires. In case the START_SEND bit is not set when tx_wait expires and MILLER_SYNC_ENABLE is set the transmission is started on the bit-grid. The guard time tx_wait is started after the end of a reception, no matter if the frame is correct or erroneous. The tx_wait guard time counter is not started in case the reception is restarted because of an EMD-event or in case the RX_MULTIPLE_ENABLE bit is set to 1. In case the register flag TX_WAIT_RFON_ENABLE is set to 1 the guard time counter is started when the devices own RF-Field is switched on. To start a transmission, it is always necessary for the firmware to set the START_SEND bit in the SYSTEM_CONFIG register or sending the instruction SEND_DATA. Having said that it is possible to disable the guard time tx_wait by setting the register TX_WAIT_CONFIG to 00h. 16 77 12.99 17 76 13.64 18 75 14.29 19 74 14.94 20 72 16.28 21 70 17.65 22 68 19.05 23 65 21.21 24 60 25 25 55 29.03 26 45 37.93 27 40 42.86 28 35 48.15 29 30 53.85 30 25 60 31 0 100 Table 60.
