Interrupt Manual Assertion

15.2.3
It is possible to manually generate an interrupt on the INT1 and INT2 pins by setting mpu_stim_intrq_st. This feature is designed for
debug use and not intended for use in normal operation. The appropriate mask bit must be set to generate an interrupt at the pin.
mpu_stim_intrq, IO, Address 0x40[2]
This control is used to set a manual interrupt. This feature should be used for test purposes only. Note that the appropriate mask bit
must be set to generate an interrupt at the pin.

mpu_stim_intrq_mb1, IO, Address 0x4B[7]
This control is used to set the INT1 interrupt mask for the manual forced interrupt signal. When set, the manual forced interrupt
triggers the INT1 interrupt and mpu_stim_intrq_st indicates the interrupt status.
Function
mpu_stim_intrq_mb1
0 

mpu_stim_intrq_mb2, IO, Address 0x4A[7]
This control is used to set the INT2 interrupt mask for the manual forced interrupt signal. When set, the manual forced interrupt
triggers the INT2 interrupt and mpu_stim_intrq_st indicates the interrupt status.
