written to bit 4 of either Device+Head Task File register while the value being written to bit 4 is written to the
“shadow” Device Select bit.
Internal Register Space – Base Address 3
Access to this register is modified by the “shadow” Channel 1/3 Device Select bit.
These registers are 32-bits wide and define the internal operation of the SiI3114. The access types are defined as
follows: R=read, W=write, and C=clearable by some write operation. Access to this register is through the PCI I/O
space. Table 20 shows the internal register space for base 3 addresses.

This register defines one of the Channel 1/3 Task File registers in the SiI3114. The register bits are also mapped
to Base Address 5, Offset C8H. See “Channel X Task File Register 2” section on page 63 for bit definitions. The
value in the “shadow” Channel 1/3 Device Select bit is used to select the Task File registers for either Channel 1
(Master; bit is 0) or Channel 3 (Slave; bit is 1).
