RESET AND CLOCK CONTROL UNIT (RCCU)
5.4 RESET/STOP MANAGER
The RESET/STOP Manager resets the device
when one of the three following triggering events
occurs:
– A hardware reset, consequence of a falling edge
on the RESET pin.
– A software reset, consequence of an HALT in-
struction when enabled.
– A Watchdog end of count.
The RESET input is schmitt triggered.
Note: The memorized Internal Reset (called RE-
SETI) will be maintained active for a duration of
32768 Oscin periods (about 8 ms for a 4 MHz crys-
tal) after the external input is released (set high).
This RESETI internal Reset signal is output on the
I/O port bit P5.0 (active low) during the whole reset
phase until the P5.0 configuration is changed by
software. The true internal reset (to all macrocells)
will only be released 511 Reference clock periods
after the Memorized Internal reset is released.
It is possible to know which was the last RESET
triggering event, by reading bits 5 and 6 of register
CLK_FLAG.
