Use of the RF interface pins and RF modes of operation are controlled through several bits of modem
Control_B Register 07.
highlighted.
The RF interface control bits include:
Freescale Semiconductor
•
•
•
RF_switch_mode (Bit 12) — This bit selects Dual Port Mode versus Single Port Mode:
— The default condition (Bit 12 = 0) is Dual Port Mode where the RF inputs are RFIN_M and
— When Bit = 1, the Single Port Mode is selected where RFIN_M (PAO_M) and RFIN_P
Ct_bias_en (Bit 14) — This bit is the enable for the CT_Bias output. When Bit 14 = 0 (default),
the CT_Bias is disabled and stays in a Hi-Z or tri-stated condition. When Bit 14 = 1, the CT_Bias
output is active and its state is controlled by the selected mode (Bit 12), ct_bias_inv, and operation
of the radio.
Ct_bias_inv (Bit 13) — This bit only affects the state of CT_Bias when Dual Port Mode is selected
and CT_bias is active. The CT_Bias changes state in Dual Port Mode based on the TX or RX state
of the radio. The ct_bias_inv bit causes the sense of the active state to change or invert based on
Bit 13’s setting. In this manner, the user can select the CT_Bias as a control signal for external
components and make the control signal active high or active low.
Controlling RF Modes of Operation
RFIN_P and the RF outputs are PAO_M and PAO_P, and operation is as described in
