of the interrupt mask register <CMask15:13> setting and the current standby mode determines
which interrupt source will be used to terminate the standby mode. The interrupt mask register is part
of the Status register in the TX19 processor core's system control coprocessor (CP0). Details are
given in Table 3.3.7.
varies according to the interrupt enable status. If the interrupt level which was set before the device
entered the standby mode is greater than or equal to the value in the interrupt mask register, the
processor services the requested interrupt after exiting the standby mode and then begins executing
instructions starting with the one following the instruction to enter the standby mode (i.e., the
instruction which specified the appropriate Config register bit). If the interrupt request level is less
than the value in the interrupt mask register, the processor immediately begins executing instructions
starting with the one following the instruction to enter the standby mode (i.e., the instruction which
specified the appropriate Config register bit) without servicing the requested interrupt. (The interrupt
request flag remains 1.)

(After released by an interrupt, other settings are also retained in the state in which they were placed
immediately before the standby mode was entered.)
