Interrupt Duration
The interrupt duration can be programmed independently for INT1 and INT2. When an interrupt event occurs, the interrupt pin INT1
or INT2 becomes active with a programmable duration as described below.
INTRQ_DUR_SEL[1:0] , IO, Address 0x40[7:6]
A control to select the interrupt signal duration for the interrupt signal on INT1.
Function
INTRQ_DUR_SEL[1:0]
00 (default)
01
10
11
INTRQ2_DUR_SEL[1:0] , IO, Address 0x41[7:6]
A control to select the interrupt signal duration for the interrupt signal on INT2.
Function
INTRQ2_DUR_SEL[1:0]
00 (default)
01
10
11
Interrupt Drive Level
The drive level of INT1 and INT2 can be programmed as described below.
INTRQ_OP_SEL[1:0] , IO, Address 0x40[1:0]
Interrupt signal configuration control for INT1.
Function
INTRQ_OP_SEL[1:0]
00 (default)
01
10
11
INT2_POL , IO, Address 0x41[2]
INT2 polarity control.
Function
INT2_POL
0 (default)
1
Interrupt Manual Assertion
It is possible to manually generate an interrupt on the INT1 and INT2 pins by setting MPU_STIM_INTRQ. 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]
Manual interrupt set control. 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.
Function
MPU_STIM_INTRQ
0 (default)
1
