TABLE 24 - INDIRECT ACCESS BLOCK BASES FOR COMMON MODULE
Register offset
The register offset is shown in the section where the register is defined. The
register offset is referred to as, “Register_offset”, in this document. A register
reference takes the formof, “[Register_offset 0xHH]”, where HH is the
hexadecimal value of the register offset.
Indirect register access
Indirect register write access
An indirect write access is initiated by first checking for IND_BUSY=0 in the
indirect access control register, and then writing data into the indirect access data
registers. Next, the address is written into the indirect access address registers.
Then, 0x00 is written into the indirect access control register. The status of the
IND_BUSY flag in the indirect access control register is checked to ensure the
process has completed before another indirect access can be initiated.
Indirect register read access
An indirect read access is initiated by first checking for IND_BUSY=0 in the
indirect access control register, and then writing the address into the indirect
access address registers. Then, 0x40 is written into the indirect access control
register. The status of the IND_BUSY flag in the indirect access control register
is checked to ensure the process has completed, and then data is read out from
the indirect access data registers.
The registers for controlling indirect register access are shown below. The
registers for controlling indirect register access are directly accessible with read
and write access.
