CRAM Structure
Coefficient RAM (CRAM) is used to store the individual coefficients calculated for each
channel. The coefficients can be written and read through the Microcontroller Interface.
The IM, FRX, FRR, AX, AR, TG1, TG2, and TH coefficients are accessed through the
Coefficient Operation (COP) Command Sequences which include the channel address
(see
Programmer’s Reference Manual
Chapter 6.5
).
Channel-specific coefficients always belong to their designated channel. Common
coefficients (TH) can be assigned to any of the four channels through field TH-SEL in
CR0 (see
Figure 25
).
