Memory programming
Error reporting
What to do if the busy bit is set:
The Service access port may not be able to complete all accesses as requested. This may be
because the address is invalid, the addressed area is read-only or cannot handle byte/halfword
accesses, or because the chip is set in a protected mode where only limited accesses are
allowed.
The error bit is updated when an access completes, and is cleared when a new access starts.
What to do if the error bit is set:
The High-Speed Bus (HSB) in the device is mapped as a slave on the SAB. This enables all
HSB-mapped memories to be read or written through the SAB using JTAG instructions, as
described in
Internal SRAM can always be directly accessed. External static memory or SDRAM can be
accessed if the EBI has been correctly configured to access this memory. It is also possible to
access the configuration registers for these modules to set up the correct configuration. Simi-
larly, external parallel flash can be programmed by accessing the registers for the flash device
through the EBI.
The internal flash and fuses can likewise be programmed by accessing the registers in the Flash
Controller. When the security fuse is set, access to internal memory is blocked, and the
CHIP_ERASE instruction must be used to erase the fuse and flash contents. For detail see the
SAB address map section.
