TIR11: Transmit Sequence Control

This register is the Transmit Sequence Control. The bits in this register determine the function of the transmit sequence signals.

Bit	Name	Reset Value	Description
7	RXCD	pin	RXC/IRQ10 pin Data. The value that is written to this bit will be
			driven out to the RXC pin when the RXCEN bit of TCR15 has been
			set to a 1 and the RXCFN bit of TCR28 has been set to a 0.
			The value that is read from RXCD represents the current value of
			the RXC/IRQ10 pin. The control of the function of the RXC/IRQ10
			pin is described in the Multi-Function Pin section.
6	USER6D	pin	USER6/IRQ5 pin Data. The value that is written to USER6D may be
			driven out to the USER6/IRQ5 pin, depending upon the values of
			the USER6EN bit (TCR15[3]), the USER6FN bit (TCR7[6]), the ISA
			PnP registers 70h and 71h, and the operating mode of the
			Am79C930 device.
			The value read from USER6D will always represent the current
			value of the USER6/IRQ5 pin. The control of the function of the
			USER6/IRQ5 pin is described in the Multi-Function Pin section.
5	USER5D	pin	USER5/IRQ4 pin Data. The value that is written to USER5D may be
			driven out to the USER5/IRQ4 pin, depending upon the values of
			the USER5EN bit (TCR15[2]), the USER5FN bit (TCR7[5]), the ISA
			PnP registers 70h and 71h, and the operating mode of the
			Am79C930 device.
			The value read from USER5D will always represent the current
			value of the USER5/IRQ4 pin. The control of the function of the
			USER5/IRQ4 pin is described in the Multi-Function Pin section.
4	LLOCKE	pin	LLOCKE pin data value. The value that is written to LLOCKE may
			be driven out to the LLOCKE/SA15 pin, depending upon the values
			of the LLOCKEN bit (TCR14[6]), and the operating mode of the
			Am79C930 device (i.e., PCMCIA or ISA).
			The value read from LLOCKE will always represent the current
			value of the LLOCKE/SA15 pin. The control of the function of the
			LLOCKE/SA15 pin is described in the Multi-Function Pin section.
3	RCEN	0	Register Control Enable. Used to control the functional timing of
			the TXCMD, TXMOD and TXPE pin values as defined in the
			Multi-Function Pin section. See the Multi-Function Pin section de-
			scription for each of these pins for more details.
2	TXMOD	0	TXMOD pin control. Used to control the functional timing of the
			TXCMD, pin value as defined in the Multi-Function Pin section. See
			the Multi-Function Pin section description for more details.
1	TXPE	0	TXPE pin control. The TXPE bit affects the value of the TXPE pin as
			described in the Multi-Function Pin section.
0	TXCMD	0	TXCMD and TXCMD pin control. The TXCMD bit affects the value
			of the the TXCMD and TXCMD pins as described in the Multi-Func-
			tion Pin section.
