4 OHCI Registers
The OHCI registers defined by the
1394 Open Host Controller Interface Specification
are memory-mapped into a
2K-byte region of memory pointed to by the OHCI base address register at offset 10h in PCI configuration space (see
Section 3.9,
OHCI Base Address Register
). These registers are the primary interface for controlling the TSB82AA2
IEEE 1394 link function.
This section provides the register interface and bit descriptions. Several set/clear register pairs in this programming
model are implemented to solve various issues with typical read-modify-write control registers. There are two
addresses for a set/clear register: RegisterSet and RegisterClear. See Table 41 for a register listing. A 1 bit written
to RegisterSet causes the corresponding bit in the set/clear register to be set to 1; a 0 bit leaves the corresponding
bit unaffected. A 1 bit written to RegisterClear causes the corresponding bit in the set/clear register to be cleared;
a 0 bit leaves the corresponding bit in the set/clear register unaffected.
Typically, a read from either RegisterSet or RegisterClear returns the contents of the set or clear register, respectively.
However, sometimes reading the RegisterClear provides a masked version of the set or clear register. The interrupt
event register is an example of this behavior.
