Revision 1.2
B.
The following table shows the factory parameters of the Information Block.
RevisionCode Interpretation
The information block includes factory parameters that are saved during device production and are used for various calibrations.
This information may be read by the core. The core accesses the Information Block using indirect byte/word read access.
To read from the Information Block, the byte or word address must be stored in IBAI register, and data bytes/words must be
read using a byte/word read operation from IBD register.
Information Block Access Index Register (IBAI)
This register defines address bits 7-0 for the read transaction from the Information Block.
Location: 00 F880
Type:
Information Block Data Register (IBD)
This register holds the data for the read transaction from the Information Block. Byte or word reads from this register are
allowed to access a byte or word pointed to by IBAI register.
