The logic behaviour of the MPI's chip select and read/write operations has been summarized in the following

table:

Bit

Symbol

Bit function

0

IAR0

Bit 0 of the status detector bits selection code

1

IAR1

Bit 1 of the status detector bits selection code

2

IAR2

Bit 2 of the status detector bits selection code

3

IAR3:

T (read)

I (write)

T bit (read only): Logical 0 when chip’s temperature is below 160°C

Logical 1 when chip’s temperature exceeds 160°C

I bit (write only): Logical 0 to disable the interrupt generation

Logical 1 to enable the interrupt generation
