Current bus cycle is completed or aborted.
Switches asinchronously with RSTIN, sinchronously upon software or watchdog reset.
The reset condition ends here. The C 167CR starts program execution.
Activation of the IO pins is controlled by software.
Execution of the EINIT instruction.
The shaded area designates the internal reset sequence, which starts after synchronization of RSTIN.
A short hardware reset is extended until the end of the reset sequence in Bidirectional reset mode.
A software or WDT reset activates the RSTIN line in Bidirectional reset mode.
