Types of Commands and Data Bytes
Coefficients and register contents are programmed and accessed through command
sequences via the Microcontroller Interface. There are three types of command
sequences:
E
x
tended
Op
eration (XOP) for access to the Common Configuration Registers (XR0
to XR7) including the Control Registers for the signaling interface.
S
tatus
Op
eration (SOP) for access to the Channel-Specific Registers (CR0 to CR5),
e.g. enabling and disabling of filters, time slot assignment, and test loops.
C
oefficient
Op
eration (COP) for access to the CRAM structures. Coefficients can be
written to the SICOFI
4-μC, and also read back.
Table 33
Types of Commands and Data Bytes.
With the first byte received via DIN, a command type is selected through bits 3 and 4. A
two-bit address field (AD) in the COP and SOP commands allows access to the
channel-specific structures (CRAM and CR registers). Since the XR Registers are
common for all channels, no address field is required within the XOP command byte.
All three commands allow read and write access, which is indicated by bit 5 (RW). The
bit fields LSEL and CODE specify the type and the length of data that follows the
command.
