Power-on reset and manual reset are available. These sources are follows.
(1)
• Input low level via PRESET pin.
• The WDTCNT overflows when the WT/IT bit in the WTCSR is 1, and the RSTS bit is 0.
• The H-UDI reset occurs (for details, see section 30, User Debugging Interface (H-UDI)).
(2)
• When a general exception other than a user break occurs while the BL bit is set to 1 in SR
• When the WDTCNT overflows while the WT/IT bit and the RSTS bit are set to 1 in WTCSR.
