66 / 232 page  Resets, Interrupts, and System Configuration MC9S08RC/RD/RE/RG 66 Freescale Semiconductor Figure 5-3 System Reset Status (SRS) POR — Power-On Reset Reset was caused by the power-on detection logic. Because the internal supply voltage was ramping up at the time, the low-voltage reset (LVR) status bit is also set to indicate that the reset occurred while the internal supply was below the LVR threshold. 1 = POR caused reset. 0 = Reset not caused by POR. PIN — External Reset Pin Reset was caused by an active-low level on the external reset pin. 1 = Reset came from external reset pin. 0 = Reset not caused by external reset pin. COP — Computer Operating Properly (COP) Watchdog Reset was caused by the COP watchdog timer timing out. This reset source may be blocked by COPE = 0. 1 = Reset caused by COP timeout. 0 = Reset not caused by COP timeout. ILOP — Illegal Opcode Reset was caused by an attempt to execute an unimplemented or illegal opcode. The STOP instruction is considered illegal if stop is disabled by STOPE = 0 in the SOPT register. The BGND instruction is considered illegal if active background mode is disabled by ENBDM = 0 in the BDCSC register. 1 = Reset caused by an illegal opcode. 0 = Reset not caused by an illegal opcode. ILAD — Illegal Address Access Reset was caused by an attempt to access a designated illegal address. 1 = Reset caused by an illegal address access 0 = Reset not caused by an illegal address access Bit 7 6 54321 Bit 0 Read: POR PIN COP ILOP ILAD(1) NOTES: 1. The ILAD bit is only present in 16K and 8K versions of the devices. 0 LVD 0 Write: Writing any value to SRS address clears COP watchdog timer. Power-on reset: 1 0 000010 Low-voltage reset: U 0 000010 Any other reset: 0 (2) 2. Any of these reset sources that are active at the time of reset will cause the corresponding bit(s) to be set; bits corresponding to sources that are not active at the time of reset will be cleared. (2) (2) (2) 000 U = Unaffected by reset |
