Error Reporting
Protected Reporting
The Service Access Bus 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:
A protected status may be reported during Shift-IR or Shift-DR. This indicates that the security
bit in the Flash Controller is set and that the chip is locked for access, according to
34.5.1.
The protected state is reported when:
What to do if the protected bit is set:
• During Shift-DR of read data: The read data is invalid. The SAB stays in data mode. Repeat
• During Shift-DR of write data: The write data is ignored. The SAB stays in data mode. Repeat
• During Shift-IR: The new instruction is selected. The last operation performed using the old
• During Shift-DR of an address: The previous operation failed. The new address is accepted.
• During Shift-DR of read data: The read operation failed, and the read data is invalid.
• During Shift-DR of write data: The previous write operation failed. The new data is accepted
• While polling with CANCEL_ACCESS: The previous access was cancelled. It may or may not
