42 / 139 page  HT66F03/HT66F04/HT68F03/HT68F04 Rev. 1.00 42 April 16, 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. Note that where more than one package type exists the table will reflect the situation for the larger package type. · HT66F03 Register Register Reset (Power-on) RES or LVR Reset WDT Time-out (Normal Operation) WDT Time-out (IDLE) MP0 xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu MP1 xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu BP - - - - - - - 0 - - - - - - - 0 - - - - - - - 0 - - - - - - - u ACC xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu PCL 0000 0000 0000 0000 0000 0000 0000 0000 TBLP xxxx xxxx uuuu uuuu uuuu uuuu uuuu uuuu TBLH -- xx xxxx -- uu uuuu -- uu uuuu -- uu uuuu TBHP - - - - - - xx - - - - - - uu - - - - - - uu - - - - - - uu STATUS -- 00 xxxx -- uu uuuu -- 1u uuuu -- 11 uuuu SMOD 0000 0011 0000 0011 0000 0011 uuuu uuuu LVDC -- 00 - 000 -- 00 - 000 -- 00 - 000 -- uu - uuu INTEG - - - - - - 00 - - - - - - 00 - - - - - - 00 - - - - - - uu INTC0 - 000 0000 - 000 0000 - 000 0000 - uuu uuuu INTC1 0000 0000 0000 0000 0000 0000 uuuu uuuu INTC2 - - - 0 - - - 0 - - - 0 - - - 0 - - - 0 - - - 0 - - - u - - - u MFI0 0000 0000 0000 0000 0000 0000 uuuu uuuu MFI2 -- 00 -- 00 -- 00 -- 00 -- 00 -- 00 -- uu -- uu PA 1111 1111 1111 1111 1111 1111 uuuu uuuu PAC 1111 1111 1111 1111 1111 1111 uuuu uuuu PAPU 0000 0000 0000 0000 0000 0000 uuuu uuuu PAWU 0000 0000 0000 0000 0000 0000 uuuu uuuu PRM 0101 0000 0101 0000 0101 0000 uuuu uuuu WDTC 0111 1010 0111 1010 0111 1010 uuuu uuuu TBC 0011 0111 0011 0111 0011 0111 uuuu uuuu EEA -- xx xxxx -- xx xxxx -- xx xxxx -- uu uuuu EED xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu EEC ---- 0000 ---- 0000 ---- 0000 ---- uuuu ADRL (ADRFS=0) xxxx ---- xxxx ---- xxxx ---- uuuu ---- ADRL (ADRFS=1) xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu ADRH (ADRFS=0) xxxx xxxx xxxx xxxx xxxx xxxx uuuu uuuu ADRH (ADRFS=1) ---- xxxx ---- xxxx ---- xxxx ---- uuuu ADCR0 0110 -- 00 0110 -- 00 0110 -- 00 uuuu -- uu ADCR1 00 - 0 - 000 00 - 0 - 000 00 - 0 - 000 uu - u - uuu ACERL ---- 1111 ---- 1111 ---- 1111 ---- uuuu |
