6.3 RESET input
6.4 Power-on reset
Table 4.
Write = channel selection; Read = channel status
The RESET input is an active LOW signal which may be used to recover from a bus fault
condition. By asserting this signal LOW for a minimum of t
register and I
RESET input must be connected to V
When power is applied to V
a reset condition until V
and the PCA9547 register and I
causing all the channels to be deselected except channel 0. Thereafter, V
lowered below 0.2 V to reset the device.
