Table 18. Register Contents to Configure the Interrupt Pin CONTROL2 REGISTER CONTENTS: DETERMINE INTERRUPT PIN FUNCTIONALITY I_FLAG_EN T_FLAG_EN (CURRENT (THERMAL OVERLOAD) OVERLOAD) FUNCTION D7 D6 D5 POR (default values) undefined 0 0 No interrupt 0 0 0 Interrupt on thermal overload only 0 0 1 Interrupt on current overload only 0 1 0 Interrupt on thermal or current 0 1 1 overload TSENSE Pin (10) The TSENSE pin is internally connected to the anode of a temperature-sensing diode located within the PA output stage. Figure 45 shows a remote junction temperature sensor circuit that can be used to measure the junction temperature of AFE031. Measuring the junction temperature of the AFE031 is optional and not required. Figure 45. Interfacing the TMP411 to the AFE031 Tx_FLAG (Pin 47) The Tx_FLAG pin is an open drain output that indicates the readiness of the Tx signal path for transmission. When the Tx_FLAG pin is high, the transmit signal path is enabled and ready for transmission. When the Tx_FLAG pin is low, the transmit path is not ready for transmission. Rx_FLAG (Pin 48) The Rx_FLAG pin is an open drain output that indicates the readiness of the Rx signal path for transmission. When the Rx_FLAG pin is high, the transmit signal path is enabled and ready for transmission. When the Rx_FLAG pin is low, the transmit path is not ready for transmission.
