This section defines the signals and external interface of
the CS4210. Figure 2-1 shows the pins organized by their
functional groupings (internal test and electrical pins are
not shown).
Signal Definitions
2.1
The tables in this section use several common abbrevia-
tions. Table 2-1 lists the mnemonics and their meanings.
PIN ASSIGNMENT
Figure 2-2 on page 9 shows the pin assignment for the
CS4210 with Tables 2-2 and 2-3, on pages 10 and 11, list-
ing the pin assignments sorted by pin number and alpha-
betically by signal name.
Section 2.2 "Signal Descriptions" starting on page 12 pro-
vides a description for each signal within its associated
functional group.
