has occurred in the device. Reading the Timer Interrupt Indication regis-
ter and the Interrupt Module Indication registers will find whether the
timer interrupt occurs or in which function block the interrupt occurs.
the TMOVE bit in the Timer Interrupt Control register is enabled, the one
second timer of the device generates an interrupt. Then the source is
served after it is found.
in the corresponding function block. To find the eventual interrupt
sources, the Interrupt Indication and Status bits in the block are polled if
their Interrupt Enable bits are enabled. Then the sources are served
after they are found.
