7.3.1.1 Disable interrupt output pin (bit 5)
7.3.1.2 Outputs change on STOP (bit 4)
7.3.1 MODE — Mode register
Table 6.
Legend: * default value.
This feature is useful when the host/micro/master does not want the INT pin to toggle
when interrupts occur. Within PCA9629, when interrupts are enabled and interrupt event
occurs, the actions related to the interrupt event are still carried out. However, if bit 5 = 1,
the INT pin does not show the activation of interrupt because the pin is disabled. If
bit 5 = 0, the micro sees the actual status of the INT pin.
The only exception to this rule is when the watchdog timer is enabled in the ‘Interrupt and
Reset’ mode (see
watchdog timer times out (even though bit 5 of this register is a ‘1’). This is because in the
‘Interrupt and Reset mode’ the part gets reset (and hence bit 5 is cleared) when the timer
times out.
This feature can be used to synchronize the starting of the motor across multiple
PCA9629 devices on the bus at approximately the same time (within few microseconds of
one another). The host controller can program all the PCA9629s on the bus and then
issue the I
devices on the bus start generating pulse sequences required to turn the motor. This
feature is applicable only to the motor coil outputs of the device namely, OUT0 to OUT3.
It is not applicable to the general purpose I/Os (P0 to P3).
