FUNCTIONAL DESCRIPTION
IDT82V2082
All digital input pins will tolerate 5.0
The chip can be reset in two ways:
Software Reset: Writing to the RST register (01H) will reset the chip
in 1 µs.
Hardware Reset: Asserting the RST pin low for a minimum of 100 ns
will reset the chip.

flip-flops are reset, and all the registers are initialized to default values.
When performing a software reset, the T1E1 bit (GCF0) will not be reset
and stay with the set value.
3.16 POWER SUPPLY
After reset, all drivers output are in high impedance state, all the internal
This chip uses a single 3.3 V power supply.
During Hardware Reset, the device requires an active clock on MCLK.
For T1/J1 operation, bit T1E1 (GCF0) is set after reset. Before access-
ing any other regisers a delay of 50 us is required to allow the internal
clocking to be settled.
