MCU InitializationSequence
When a reset occurs the stackis reset to program
counter, the PC is loaded with the address of the
reset vector (located in the program ROM at ad-
dresses FFEh & FFFh). A jump instruction to the
beginning of the program has to be written into
these locations. After a reset the interrupt mask is
automatically activated so that the Core is in non-
maskable interrupt mode to prevent false or ghost
interrupts during the restart phase. Therefore the
restart routine should be terminated by a RETIin-
struction to switch to normal mode and enable in-
terrupts. If no pending interrupt is present at the
end of the reset routine, the ST639x will continue
with the instruction after the RETI; otherwise the
pendinginterrupt will beserviced.
RESET Low Power Mode
(ST6392 andST6399 only)
When the reset pin is low, the quartz oscillator is
Disabled allowing reduced current consumption.
When the reset pin is raised the quartzoscillator is
enabled and oscillations will start to build up.The
internal reset circuitrywill count 2048clockson the
oscillator pin beforeallowingthe MCUto go out of
