Internal Register Space – Base Address 5
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
Memory space. Base Address 5 accesses can be disabled by setting input BA5_EN low. Table 22 shows the
internal register space for base 5 addresses.
