INTO SLAVE**

The MAX1608/MAX1609 can generate hardware inter-

rupts whenever the logic states of the IO_ pins change

or when thermal shutdown occurs. Interrupts are sig-

naled on the ALERT pin. The IO_ interrupts can be

masked individually through the mask registers.

Registers NDR2 and SDR2 mask the IO_ rising-edge

interrupts, while NDR3 and SDR3 mask the IO_ falling-

edge interrupts. The power-on-reset state masks all

interrupts (Tables 4 and 5).

STOP

The thermal-shutdown protection also generates an

interrupt. This interrupt cannot be masked (see Thermal

Shutdown section). An interrupt can be cleared with a

SPOR or an Alert Response. However, after an interrupt

has occurred, masking will not clear it.

Alert Response Address (0b00011001)

The alert response (interrupt pointer) address provides

quick fault identification for simple slave devices that

cannot initiate communication as a bus master. When a

slave device generates an interrupt, the host (bus mas-

ter) interrogates the bus slave devices through a special

receive-byte operation that includes the alert response

address (0x19). The offending slave device returns its

own address during this receive-byte operation.

**DURING A RECEIVE-BYTE PROTOCOL, CORRESPONDS TO THE R/W BIT. DURING A

The interrupt pointer address can activate several dif-

ferent slave devices simultaneously. If more than one
