Pin Function Description
Control Register Definitions
Control Register Functions
Control register functions are summarized in Table
1.
Capture Engine parameter registers have no prefix;
Command and Status registers are prefixed by 1; Encoder
parameter registers are prefixed by 2.
Each internal register is 10-bits wide. To access a register two
8-bit data words must be transferred. In the case of a write,
writing the second byte loads the internal 10-bit
register. Most registers have type read/write. Read only
registers access the internal status of the TMC2376.
Write-only registers initiate the transfer of data.
For typical settings, see Video Formats/Register Settings.
