Interrupt Mask, Address 25 (0x19) (continued)
Note
pin reflects the state of bit 26.15. Clearing this bit only inhibits the MDINT pin from
being asserted.
Interrupt Status
The status of interrupts already written to the device are available for reading from
register 26 in the main registers space. The following table lists the readouts you can
expect.

All set bits in this register are cleared after being read (self-clearing). If bit 26.15 is
set, the cause of the interrupt can be read by reading bits 26.14:0.
For bits 26.14 and 26.12, bit 0.12 must be set for this interrupt to assert.
For bit 26.2, bits 4.8:5 must be set for this interrupt to assert.
