32.7.8 Go <address> <mode>
When the GO command is used, execution begins at the specified address (assuming it is
an executable address) with the device left as it was configured for the ISP code. This
means that some things are different than they would be for entering user code directly
following a chip reset. Most importantly, the main PLL will be running and connected,
configured to generate a CPU clock with a frequency of approximately 14.7456 MHz.
32.7.9 Erase sector(s) <start sector number> <end sector number>
Table 579. ISP Go command
Command G
Input Address: Flash or RAM address from which the code execution is to be started.
This address should be on a word boundary.
Mode (retained for backward compatibility): T (Execute program in Thumb
Mode) | A (not allowed).
Return Code CMD_SUCCESS |
ADDR_ERROR |
ADDR_NOT_MAPPED |
CMD_LOCKED |
PARAM_ERROR |
CODE_READ_PROTECTION_ENABLED
Description This command is used to execute a program residing in RAM or flash memory. It
may not be possible to return to the ISP command handler once this command is
successfully executed. This command is blocked when any level of code read
protection is enabled.
Example "G 0 T<CR><LF>" branches to address 0x0000 0000.
Table 580. ISP Erase sector command
Command E
Input Start Sector Number
End Sector Number:
Should be greater than or equal to start sector number.
Return Code CMD_SUCCESS |
BUSY |
INVALID_SECTOR |
SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION |
CMD_LOCKED |
PARAM_ERROR |
CODE_READ_PROTECTION_ENABLED
Description This command is used to erase one or more sector(s) of on-chip flash memory. This
command is blocked when code read protection level CRP3 is enabled. When code
read protection level CRP1 is enabled, individual sectors other than sector 0 can be
erased. All sectors can be erased at once in CRP1 and CRP2.
Example "E 2 3<CR><LF>" erases the flash sectors 2 and 3.
