RETE – Return from event handler
Architecture revision:
Architecture revision1 and higher.
Description
Returns from an exception or interrupt. SREG[L] is cleared to support atomical memory access
with the stcond instruction. This instruction can only be executed in INT0-INT3, EX and NMI
modes. Execution in Application or Supervisor modes will trigger a Privilege Violation exception.
