CC1312PSIP: Regulation of TX power vs VDDS (3.3V-3.8V)

TX power is regulated for power supply voltage changes in the CC1312PSIP device. This reduces the effect of increasing VDDS on the TX power and limits the TX power from going much higher than 20 dBm. The TX power regulation is applied when VDDS > 3.3V and the device is set to transmit 17 dBm or above.

Under these conditions, the feature maintains the TX power close to the original power setting even when VDDS is increased. For TX power setting below 17 dBm, the feature has no effect on the device behavior.

RF Sysconfig: Antenna Switch Hardware Changes

The antenna switch, available under “Use Hardware”, is required by P device boards (matching regex /CC....P/). To ensure correct RF performance, the correct value for this option is now selected by default in the UI, but not when adding the RF module in a config script.

Make sure this option is selected for correct RF performance. It must also be placed before any assignments related to the RF module for coex.

See snippet below to add correct hardware:

const RF = scripting.addModule("/ti/drivers/RF");
if (("board" in system.deviceData) && ("RF" in system.deviceData.board.components)) {
    RF.$hardware = system.deviceData.board.components.RF;
}
