BIT
FIELD NAME
TYPE
DESCRIPTION
22
aPhyEnhanceEnable
RSC
When bits 23 (programPhyEnable) and 17 (linkEnable) are 1, the OHCI driver can set bit 22 to
1 to use all IEEE 1394a-2000 enhancements. When bit 23 (programPhyEnable) is cleared to 0,
the software does not change PHY enhancements or this bit.
2120
RSVD
R
Reserved. Bits 2120 return 0s when read.
19
LPS
RSC
Bit 19 controls the link power status. Software must set this bit to 1 to permit link-PHY
communication. A 0 prevents link-PHY communication.
The OHCI-link is divided into two clock domains (PCI_CLK and PHY_SCLK). If software tries to
access any register in the PHY_SCLK domain while the PHY_SCLK is disabled, then a target
abort is issued by the link. This problem can be avoided by setting bit 4 (DIS_TGT_ABT) in the
miscellaneous configuration register at offset F0h in the PCI configuration space (see
Section 3.23,
Miscellaneous Configuration Register
). This allows the link to respond to these
types of request by returning all Fs (hex).
OHCI registers at offsets DChF0h and 100h11Ch are in the PHY_SCLK domain.
After setting LPS, software must wait approximately 10 ms before attempting to access any of
the OHCI registers. This gives the PHY_SCLK time to stabilize.
18
postedWriteEnable
RSC
Bit 18 enables (1) or disables (0) posted writes. Software changes this bit only when bit 17
(linkEnable) is 0.
17
linkEnable
RSC
Bit 17 is cleared to 0 by either a system (hardware) or software reset. Software must set this bit
to 1 when the system is ready to begin operation and then force a bus reset. This bit is necessary
to keep other nodes from sending transactions before the local system is ready. When this bit is
cleared, the TSB82AA2 device is logically and immediately disconnected from the 1394 bus, no
packets are received or processed, nor are packets transmitted.
16
SoftReset
RSCU
When bit 16 is set to 1, all TSB82AA2 states are reset, all FIFOs are flushed, and all OHCI
registers are set to their system (hardware) reset values, unless otherwise specified. PCI
registers are not affected by this bit. This bit remains set to 1 while the software reset is in progress
and reverts back to 0 when the reset has completed.
150
RSVD
R
Reserved. Bits 150 return 0s when read.
4.17 Self-ID Buffer Pointer Register
The self-ID buffer pointer register points to the 2K-byte aligned base address of the buffer in host memory where the
self-ID packets are stored during bus initialization. Bits 3111 are read/write accessible. Bits 100 are reserved, and
return 0s when read.
