			is set to a 0, the Baud Detect Count for Stop Diversity is not used in
			the stop diversity decision logic.
1	UBDCS	0	Use Baud Detect of Carrier Sense in CCA decision. When this bit is
			set to a 1, the Baud Detect Count for Carrier Sense becomes one
			input to the clear channel assessment logic. When this bit is set to a
			0, the Baud Detect Count for Carrier Sense is not used in the clear
			channel assessment decision.
0	URSSI	0	Use RSSI in CCA and Stop Diversity decisions. When this bit is set
			to a 1, the RSSI converted value comparison to the RSSI lower limit
			becomes one input to the clear channel assessment logic and also
			becomes one input to the Stop Diversity decision logic. When this
			bit is set to a 0, the RSSI converted value comparison to the RSSI
			lower limit is not used in the clear channel assessment logic and is
			also not used in the Stop Diversity decision logic.

TCR29: Reserved

This register is a TAI reserved location.

CONFIGURATION REGISTER INDEX:			1Dh
Bit	Name	Reset Value	Description
7–0	Reserved	–	Reserved. Must be written as a 0. Reads of this bit produce
			undefined data.

TCR30: Pin Function and Data Rate

This register is the Pin Function and Data Rate control register. This register contains bits that control the

function of the ANTSLT, TXDATA, TXCMD, and TXC pins as well as control bits to set the network data rate.

CONFIGURATION REGISTER INDEX:			1Eh
Bit	Name	Reset Value	Description
7	ANTSLTLFN	0	ANTSLT Function. ANTSLTLFN, ANTSLTLEN (TCR15[7]),
			ANTSEN (TIR26[3]), and the PCMCIA pin are used to determine
			the direction and data of the ANTSLT pin.
			The control of the function of the ANTSLT/LA23 pin is described in
			the Multi-Function Pin section.
6	TXDLFN	0	TXDATA Function. TXDLFN, TXDLEN (TCR15[6]), and the
			PCMCIA pin are used to determine the direction and data of the
			TXDATA pin.
			The control of the function of the TXDATA/LA23 pin is described in
			the Multi-Function Pin section.
5	TXCMFN	0	TXCMD Function. TXCMFN, TXCMEN (TCR15[5]), RCEN
			(TIR11[3]), and the PCMCIA pin are used to determine the function
			of the TXCMD pin.
4	USER7FN	–	Reserved. Must be written as 0. Reads of this produce
			undefined data.
			The control of the function of the TXCMD/LA21 pin is described in
			the Multi-Function Pin section.
3	TXCIN	1	TXC Input. When set to a 0, the TXC pin functions as an output, pro-
			viding a divide by X version of the CLKIN input, where X is deter-
			mined by the setting of the DR bits of TCR30. When set to a 1, the
			TXC pin functions as an input, allowing the data rate of the transmit
			operations to be set by an external source. When TXCIN is set to 1,
