CS8420
13. HARDWARE MODES
13.1
Overall Description
The CS8420 has six Hardware modes, which allow use of the device without using a micro-controller to ac-
cess the device control registers and CS & U data. The flexibility of the CS8420 is necessarily limited in
Hardware mode. Various pins change function in Hardware mode, and various data paths are also possible.
These alternatives are identified by Hardware mode numbers 1 through 6. The following sections describe
the data flows and pin definitions for each Hardware mode.
13.1.1
Hardware Mode Definitions
Hardware mode is selected by connecting the H/S pin to ‘1’. In Hardware mode, 3 pins (DFC0, DFC1 &
S/AES) determine the Hardware mode number, according to Table 5. Start-up options are used exten-
sively in Hardware mode. Options include whether the serial audio output ports are master or slave, the
serial audio ports’ format and whether TCBL is an input or an output. Which output pins are used to set
which modes depends on which Hardware mode is being used.
13.1.2
Serial Audio Port Formats
In Hardware mode, only a limited number of alternative serial audio port formats are available. These for-
mats are described by Tables 6 and 7, which define the equivalent Software mode bit settings for each
For each Hardware mode, the following pages contain a data flow diagram, a pin-out drawing, a pin de-
scriptions list and a definition of the available start-up options.
