RESETS
(Cont’d)
3.2.6 MCU Initialization Sequence
When a reset occurs the stack is reset, the PC is
loaded with the address of the ResetVector (locat-
ed in program ROM starting at address 0FFEh). A
jump tothe beginning of theuser program must be
coded at this address. Following a Reset, the In-
terrupt flag is automatically set, so that the CPU is
in Non Maskable Interrupt mode; this prevents the
initialisation routine from being interrupted. The in-
itialisation routine should therefore be terminated
by a RETI instruction, in order to revert to normal
mode and enable interrupts. If nopending interrupt
is presentat the end of theinitialisation routine, the
MCU will continue by processing the instruction
immediately followingthe RETI instruction. If, how-
ever, a pending interrupt is present, it will be serv-
iced.
