Reset
The reset is applied asynchronously regarding XTAL clock. It can be done either by the RESET
pin or by software. The RESET pin is a CMOS trigger input with a pull-down resistor (110 kΩ).
An external 1 µF capacitor to V
provides to RESET pin an efficient behavior.
CC
The software reset is made through the GRES command bit of the Command Register (0x03).
The two resets are ored, filtered and gauged. T
he internal reset, always asserted asynchronously, enables the internal oscillator. Then it waits
for eight clock periods the oscillator stability.
The different blocks of the TSS461E need to be turned on synchronously. So the release of the
internal reset is synchronous and a loose of clock can let the TSS461E in permanent reset after
applying Reset.
