Internal Register Space – Base Address 0
Access to these registers is modified by the “shadow” Channel 0/2 Device Select bit. The “shadow” Channel 0/2
Device Select bit is written from bit 4 of the byte written to the Channel 0/2 Task File Device+Head register (06H).
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 17 shows the internal register space for base 0 addresses.

This register defines four of the Channel 0/2 Task File registers in the SiI3114. The register bits are also mapped
to Base Address 5, Offset 80H. See “Channel X Task File Register 0” section on page 62 for bit definitions. The
value in the “shadow” Channel 0/2 Device Select bit is used to select the Task File registers for either Channel 0
(Master, bit is 0) or Channel 2 (Slave, bit is 1).

This register defines four of the Channel 0/2 Task File registers in the SiI3114. The register bits are also mapped
to Base Address 5, Offset 84H. See “Channel X Task File Register 1” section on page 62 for bit definitions. Except
for writing the Device+Head Task File register, the value in the “shadow” Channel 0/2 Device Select bit is used to
select the Task File registers for either Channel 0 (Master; bit is 0) or Channel 2 (Slave; bit is 1). For writing the
Device+Head Task File register, the value being written to bit 4 of the register (the Device Select bit) is used to
select the Task File register for either Channel 0 (Master; bit is 0) or Channel 2 (Slave; bit is 1); a 0 is always
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.
