Part Number: TMS570LS3137

Hello ,

Software Reset : writing a 1 to bit 15 of System Exception Control Register (SYSECR) is resetting the processor but the SFR's are retaining the values I want the SFR's to go to Power ON reset values .

While Running TMS570LS3137 firmware in with 4 different project Switching from one project to another in same FLASH area with totally different run requirements .

So if I have to branch from FIXED decision maker to Application , I need to reset all SFR settings that FIXED DECISION MAKER has put in with the values .

FIXED DECISION MAKER address             0x00000000 to 0x00007FFF

UPGRADEBLE APPLICATION address      0x00020000 to 0x000FFFFF

BOOTLODAER APPLICATION address      0x00100000 to 0x0011FFFF

UPGRADEBLE DECISION MAKER  add    0x00120000 to 0x0015FFFF

    Hello,

    Power-on reset can be induced by driving nPORTST pin low and by the embedded Voltage monitor.

    And you are right that some registers are only reset by nPORRST. But there is no way power-on reset be induced by software.

    Best regards,
