PROGRAMMING INFORMATION
4.1
REGISTER LIST AND MAP
The IDT82V2042E registers can be divided into Global Registers and
Local Registers. The operation on the Global Registers affects both of the
two channels while the operation on Local Registers only affects the spe-
cific channel. For different channel, the address of Local Register is differ-
ent. Table-19 is the map of Global Registers and Table-20 is the map of
Local Registers. If the configuration of both of the two channels is the same,
the COPY bit (GCF, 20H) can be set to ‘1’ to establish the Broadcasting
mode. In the Broadcasting mode, the Writing operation on any of the two
channels’registerswillbecopiedtothecorrespondingregistersoftheother
channel.
4.2
Reserved Registers
When writing to registers with reserved bit locations, the default state
must be written to the reserved bits to ensure proper device operation.
