Reset Initialization
The ST70235A supports two reset modes:
– A 'hardware' reset is activated by the RESETB
– 'Soft' reset activated by the controller write
GP_OUT
Disable_Comp
pin (active low). A hard reset occurs when a low
input value is detected at the RESETB input.
The low level must be applied for at least 1ms to
guarantee a correct reset operation. All clocks
and power supplies must be stable for
200ns prior to the rising edge of the RESETB
signal.
access to a soft reset configuration bit. The reset
process takes less than 10000 MCLK clock
cycles.
