3.14 5V TOLERANT I/O PINS
All digital input pins will tolerate 5.0 ± 10% 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 (01H) will reset the chip
in 1 us.
Hardware Reset: Asserting the RST pin low for a minimum of 100
ns will reset the chip.
During Hardware Reset, the device requires an active clock on
MCLK. For T1/J1 operation, bit T1E1(GCF0) is set after reset.
Before accessing any other registers a delay of 50 us is required to
allow the internal clocking to be settled.
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.
When performing a software reset, the T1E1 bit (GCF0) will not be reset
and stay with the set value.
3.16 POWER SUPPLY
This chip uses a single 3.3 V power supply.
