PIN FUNCTION
Capacitive Touch Sensor 1
ALERT# - Active low alert / interrupt output usable for SMBus alert
(CAP1006-1)
BC_IRQ# - Active low interrupt / optional for BC-Link
(CAP1006-2)
SMDATA - Bi-directional, open-drain SMBus data - requires pull-up
resistor (CAP1006-1)
BC_DATA - Bi-directional, open-drain BC-Link data - requires pull-
up resistor (CAP1006-2)
SMCLK - SMBus clock input - requires pull-up resistor
(CAP1006-1)
BC_CLK - BC-Link clock input (CAP1006-2)
