3.13 GENERAL PURPOSE I/O
GPIO0. These two pins can be considered as digital Input or Output port
by the DIR1 bit (GPIO, A0H) and DIR0 bit (GPIO, A0H) respectively. If the
GPIO1 and GPIO0 are configured as Input port, the LEVEL1 bit (GPIO,
A0H) and the LEVEL0 bit (GPIO, A0H) are used to reflect the level of the
GPIO1 pin and the GPIO0 pin respectively. If the GPIO1 and GPIO0 are
configured as Output port, the content in the LEVEL1 bit and LEVEL0 bit
determines the logic value of GPIO1 pin and GPIO0 pin respectively.
3.14 5V TOLERANT I/O PINS
TTL logic.
The IDT82V2088 provides two general purpose digital I/O pins: GPIO1,
All digital input pins will tolerate 5.0
±
5% volts and are compatible with

3.15 RESET OPERATION
•
•
flip-flops are reset, and all the registers are initialized to default values.
3.16 POWER SUPPLY
The chip can be reset in two ways:
After reset, all drivers output are in high impedance state, all the internal
This chip uses a single 3.3 V power supply.
Software Reset: Writing to the RST register (20H) will reset the chip
in 1 us.
Hardware Reset: Asserting the RST pin low for a minimum of 100 ns
will reset the chip.
