Texas Instruments TSB12LV26 manual Subsystem Access Register, Subsystem access, Subdevid, Subvenid

Table 3±18. Link Enhancement Control Register Description (Continued)

BIT	FIELD NAME	TYPE	DESCRIPTION
			Enable acceleration enhancements. OHCI-Lynx compatible. When set to 1, this bit notifies the PHY
1	enab_accel	R/W	that the link supports the 1394a acceleration enhancements, i.e., ack-accelerated, fly-by
			concatenation, etc. It is recommended that this bit be set to 1.
0	RSVD	R	Reserved. Bit 0 returns 0 when read.

3.22 Subsystem Access Register

Write access to the subsystem access register updates the subsystem identification registers identically to OHCI-Lynx. The system ID value written to this register may also be read back from this register. See Table 3±19 for a complete description of the register contents.
