26 / 66 page ![]() HT82M75R/HT82M75RE HT82K75R/HT82K75RE Rev. 1.10 26 June 11, 2010 The different kinds of resets all affect the internal registers of the microcontroller in different ways. To ensure reliable continuation of normal program execution after a reset occurs, it is important to know what condition the microcontroller is in after a particular reset occurs. The following table describes how each type of reset affects each of the microcontroller internal registers. Register Reset (Power-on) WDT time-out (Normal Operation) RES Reset (Normal Operation) RES Reset (HALT) WDT Time-out (HALT)* PCL 000H 000H 000H 000H 000H ACC xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu uuuu uuuu TBLP xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu uuuu uuuu TBLH -xxx xxxx -uuu uuuu -uuu uuuu -uuu uuuu -uuu uuuu STATUS --00 xxxx --1u uuuu --uu uuuu --01 uuuu --11 uuuu INTC -000 0000 -000 0000 -000 0000 -000 0000 -uuu uuuu TMRL xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu TMRH xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu TMRC 00-0 1---- 00-0 1---- 00-0 1---- 00-0 1---- uu-u u--- PA 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PAC 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PB 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PBC 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PC 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PCC 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PD ** 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PDC ** 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PE ** 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu PEC ** 1111 1111 1111 1111 1111 1111 1111 1111 uuuu uuuu WDTS ---- -111 ---- -111 ---- -111 ---- -111 ---- -uuu MP0 xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu uuuu uuuu MP1 xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu uuuu uuuu CTLR 0100 0x00 0100 0x00 0100 0x00 0100 0x00 uuuu uxuu PTR 0000 0000 0000 0000 0000 0000 0000 0000 uuuu uuuu TBHP ----- 0000 ----- 0000 ----- 0000 ----- 0000 0000 uuuu SPIR 0000 0000 0000 0000 0000 0000 0000 0000 0000 uuuu SBCR 0110 0000 0110 0000 0110 0000 0110 0000 uuuu uuuu SBDR xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu Note: ²**² For the HT82K75R only ²-² not implemented ²u² means ²unchanged² ²x² means ²unknown² |
