Description of Interrupt Operation

4.6.1.1

Real Time Interrupt (RTI)

The clock source for the RTI is either IRCCLK or OSCCLK depending on the setting of the RTIOSCSEL 
bit. In Stop Mode with PSTP=1 (Pseudo Stop Mode), RTIOSCSEL=1 and PRE=1 the RTI continues to 
run, else the RTI counter halts in Stop Mode.

The RTI can be used to generate hardware interrupts at a fixed periodic rate. If enabled (by setting 
RTIE=1), this interrupt will occur at the rate selected by the CPMURTI register. At the end of the RTI 
time-out period the RTIF flag is set to one and a new RTI time-out period starts immediately.

A write to the CPMURTI register restarts the RTI time-out period.

4.6.1.2

PLL Lock Interrupt

The S12CPMU_UHV_V8 generates a PLL Lock interrupt when the lock condition (LOCK status bit) of 
the PLL changes, either from a locked state to an unlocked state or vice versa. Lock interrupts are locally 
disabled by setting the LOCKIE bit to zero. The PLL Lock interrupt flag (LOCKIF) is set to1 when the 
lock condition has changed, and is cleared to 0 by writing a 1 to the LOCKIF bit.

4.6.1.3

Oscillator Status Interrupt

When the OSCE bit is 0, then UPOSC stays 0. When OSCE=1 the UPOSC bit is set after the LOCK bit is 
set.

Upon detection of a status change (UPOSC) the OSCIF flag is set. Going into Full Stop Mode or disabling 
the oscillator can also cause a status change of UPOSC.

Any change in PLL configuration or any other event which causes the PLL lock status to be cleared leads 
to a loss of the oscillator status information as well (UPOSC=0).

Oscillator status change interrupts are locally enabled with the OSCIE bit.

NOTE

Loosing the oscillator status (UPOSC=0) affects the clock configuration of 
the system

1

. This needs to be dealt with in application software.

4.6.1.4

Low-Voltage Interrupt (LVI)

In FPM the input voltage VDDA is monitored. Whenever VDDA drops below level V

LVIA,

 the status bit 

LVDS is set to 1. When VDDA rises above level V

LVID

 the status bit LVDS is cleared to 0. An interrupt, 

indicated by flag LVIF = 1, is triggered by any change of the status bit LVDS if interrupt enable bit LVIE 
= 1.
