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 form of, “[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
indirectaccesscontrolregister,andthenwritingdataintotheindirectaccessdata
registers.Next,theaddressiswrittenintotheindirectaccessaddressregisters.
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.ThestatusoftheIND_BUSYflagintheindirectaccesscontrolregister
ischeckedtoensuretheprocesshascompleted,andthendataisreadoutfrom
the indirect access data registers.
The registers for controlling indirect register access are shown below. The
registersforcontrollingindirectregisteraccessaredirectlyaccessiblewithread
and write access.
