35 / 58 page  HT46R01A Rev. 1.10 35 August 13, 2008 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) RES or LVR Reset WDT Time-out (Normal Operation) WDT Time-out (HALT) MP0 1xxx xxxx uuuu uuuu 1uuu uuuu 1uuu uuuu MP1 1xxx xxxx uuuu uuuu 1uuu uuuu 1uuu uuuu ACC xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu TBLP xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu TBLH -- xx xxxx -- uu uuuu -- uu uuuu -- uu uuuu WDTS ---- - 111 ---- - 111 ---- - 111 ---- - uuu STATUS -- 00 xxxx -- uu uuuu -- 1u uuuu -- 11 uuuu INTC0 - 000 0000 - 000 0000 - 000 0000 - uuu uuuu TMR0 xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu TMR0C 0000 1000 0000 1000 0000 1000 uuuu uuuu PA 1111 1111 1111 1111 1111 1111 uuuu uuuu PAC 1111 1111 1111 1111 1111 1111 uuuu uuuu PAPU - 000 0000 - 000 0000 - 000 0000 - uuu uuuu PAWK 0000 0000 0000 0000 0000 0000 uuuu uuuu CTRL0 - 00 - 0000 - 00 - 0000 - 00 - 0000 - uu - uuuu CTRL1 10 -- 1010 10 -- 1010 10 -- 1010 uu -- uuuu PWM xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu ADR xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu ADCR 0100 0000 0100 0000 0100 0000 uuuu uuuu ACSR 1 --- - 000 1 --- - 000 1 --- - 000 u --- - uuu Note: ²*² means ²warm reset² ²-² not implemented ²u² means ²unchanged² ²x² means ²unknown² |
