3.13 GENERAL PURPOSE I/O
The IDT82V2048E provides two general purpose digital I/O pins:
GPIO1, GPIO0. Thesetwopinscan beconsideredasdigitalInputorOutput
port by the DIR1 bit (GPIO, A0H) and DIR0 bit (GPIO, A0H) respectively.
IftheGPIO1andGPIO0areconfiguredasInputport,theLEVEL1bit(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
All digital input pins will tolerate 5.0 ± 5% volts and are compatible with
TTL logic.
3.15 RESET OPERATION
The chip can be reset in two ways:
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.
After reset, all drivers output are in high impedance state, all the internal
flip-flops are reset, and all the registers are initialized to default values.
3.16 POWER SUPPLY
This chip uses a single 3.3 V power supply.
