The Reset Controller status register (RSTC_SR) provides several status fields:

• When in Watchdog Reset:
• RSTTYP field: This field gives the type of the last reset, as explained in previous sections.
• SRCMP bit: This field indicates that a Software Reset Command is in progress and that no
• NRSTL bit: The NRSTL bit of the Status Register gives the level of the NRST pin sampled on
• URSTS bit: A high-to-low transition of the NRST pin sets the URSTS bit of the RSTC_SR
further software reset should be performed until the end of the current one. This bit is
automatically cleared at the end of the current software reset.

register. This transition is also detected on the Master Clock (MCK) rising edge (see
12-9). If the User Reset is disabled (URSTEN = 0) and if the interruption is enabled by the
URSTIEN bit in the RSTC_MR register, the URSTS bit triggers an interrupt. Reading the
RSTC_SR status register resets the URSTS bit and clears the interrupt.
2 cycle
– The processor reset is active and so a Software Reset cannot be programmed.
