Figure 11. Operating Modes
SLEEP MODE
The 35XS3400 is in Sleep mode when:
? V PWR and V DD are within the normal voltage range,
? wake-up = 0,
? fail = X,
? fault = X.
This is the Default mode of the device after first applying
battery voltage (VPWR) prior to any I/O transitions. This is
also the state of the device when the WAKE and RST and
IN_ON[0:3] are logic [0]. In the Sleep mode, the output and
all unused internal circuitry, such as the internal regulator, are
off to minimize draw current. In addition, all SPI-configurable
features of the device are as if set to logic [0].
NORMAL MODE
In this mode and also in Fail-safe, the fault condition reset
depends on fault_control signal, as defined below:
fault_control[x] = ( (IN_ON[x] and DIR_dis[x]) and
PWM_en ) or (On bit [x]).
Programmable PWM module
The outputs HS[0:3] are controlled by the programmable
PWM module if PWM_en and On bits are set to logic [1].
The clock frequency from IN0 input pin or from internal
clock is the factor 2 7 (128) of the output PWM frequency
(CLOCK_sel bit). The outputs HS[0:3] can be controlled in
the range of 5% to 98% with a resolution of 7 bits of duty-
cycle ( Table 7 ). The state of other IN pin is ignored.
Table 7. Output PWM Resolution
The 35XS3400 is in Normal mode when:
? V PWR and V DD are within the normal voltage range,
? wake-up = 1,
? fail = 0,
? fault = 0.
In this mode, the NM bit is set to lfault_contrologic [1] and
the outputs HS[0:3] are under control, as defined by hson
signal:

Output state

PWM (1/128 duty-cycle)
PWM (2/128 duty-cycle)
PWM (3/128 duty-cycle)
PWM ((n+1)/128 duty-cycle)
fully ON
hson[x] = ( ( (IN[x] and DIR_dis[x]) or On bit[x] ) and
PWM_en ) or (On bit [x] and Duty_cycle[x] and PWM_en).
The timing includes seven programmable PWM switching
delay (number of PWM clock rising edges) to improve overall
EMC behavior of the light module ( Table 8 ).
