CLOCK MANAGEMENT (Cont’d)
7.3.6 Interrupt Generation
System clock selection modifies the CLKCTL and
CLK_FLAG registers.
The clock control unit generates an external inter-
rupt request (INTD0) in the following conditions:
– when CK_AF and CLOCK2/16 are selected or

– when the PLL loses the programmed frequency
This interrupt can be masked by resetting the
INT_SEL bit in the CLKCTL register. Note that this
is the only case in the ST9 where an interrupt is
generated with a high to low transition.
