24-Channel Automotive Switch Monitor
Serial Peripheral Interface
( CS , SDO, SDI, CLK)
The MAX13362 operates as a serial peripheral interface
(SPI) slave device. An SPI master accesses and pro-
grams the MAX13362 by reading/writing the control
registers. The control registers are 32 bits wide, have 2
command bits (or register addresses) and 30 data bits
(see Table 1). Figure 3 shows the read/write sequence
through SPI. The SPI logic counts the number of bits
clocked into the IC (using a modulo-32 counter so that
CS
CLK
daisy chaining is possible) and enables data latching
only if exactly 32 bits (or an integer multiple thereof)
have been clocked in.
Status Register
The status register contains the status of the switches
connected to IN0–IN23. The status register also con-
tains an overtemperature warning bit, a power-on-reset
bit and a device type bit (see Table 1). The status reg-
ister is accessed by the SPI-compatible interface.

BIT DESCRIPTION
Command bits. Select the internal register to which data bits D0–D29 are to be written.
Data bits.
Switch state bit. 0 = switch open, 1 = switch closed.
Overtemperature bit. When overtemperature occurs, this bit is set to 1. It is reset on the rising edge of CS .
Power-on-reset bit. It indicates whether the IC has had a power-on-reset since the last SPI read. 0 = device has
been reset. RST is set to 1 on the rising edge of CS .
Device type. 0 = reserved for future use, 1 = MAX13362.
