PIN FUNCTIONS (continued)
PIN
I/O
DESCRIPTION
NAME
NO.
Analog input2 for A/D converter TPS65070, TPS65073, TPS650731, TPS650732 only:
AD_IN2
44
I
(TSX2)
Input 2 to the x-plate for the touch screen
Analog input3 for A/D converter TPS65070, TPS65073, TPS650731, TPS650732 only:
AD_IN3
45
I
(TSY1)
Input 1 to the y-plate for the touch screen
Analog input4 for A/D converter TPS65070, TPS65073, TPS650731, TPS650732 only:
AD_IN4
46
I
(TSY2)
Input 2 to the y-plate for the touch screen
Connect a 10mF bypass cap from this pin to GND. This pin can optionally be used as a reference output
BYPASS
41
O
(2.26 V). The maximum load on this pin is 0.1mA.
Connect a 2.2mF bypass cap from this pin to GND. The pin is connected to an internal LDO providing the
INT_LDO
48
O
power for the touch screen controller (TSREF).
Open drain interrupt output. An interrupt can be generated upon:
A touch of the touch screen
INT
40
O
Voltage applied or removed at pins AC or USB
PB_IN actively pulled low (optionally actively pulled high)
The output is actively pulled low if the interrupt is active. The output goes high after the Bit causing the
interrupt in register INT has been read. The interrupt sources can be masked in register INT, so no interrupt
is generated and pin INT is pulled high with its external pull-up resistor.
CONVERTERS:
