Description
and Notes
Desc: SYS Power Good Indicator.
Notes: If hibernate is not used or the
internal Power Good Counter is used,
connect to VDD_EXT.
Desc: SYS Thermal Diode Anode.
Notes: Active during reset and hibernate.
If the thermal diode is not used, connect
to ground.
Desc: SYS Thermal Diode Cathode.
Notes: Active during reset and hibernate.
If the thermal diode is not used, connect
to ground.
Desc: SYS Crystal Output.
Notes: Leave unconnected if an oscillator
is used to provide SYS_CLKIN. Active
during reset. State during hibernate is
controlled by DPM_HIB_DIS.
Desc: TWI0 Serial Clock.
Notes: Open drain, requires external pull-
up resistor. Consult Version 2.1 of the I2C
specification for the proper resistor value.
If TWI is not used, connect to ground.
Desc: TWI0 Serial Data.
Notes: Open drain, requires external pull-
up resistor. Consult Version 2.1 of the I2C
specification for the proper resistor value.
If TWI is not used, connect to ground.
Desc: TWI1 Serial Clock.
Notes: Open drain, requires external pull-
up resistor. Consult Version 2.1 of the I2C
specification for the proper resistor value.
If TWI is not used, connect to ground.
Desc: TWI1 Serial Data.
Notes: Open drain, requires external pull-
up resistor. See the I2C-Bus Specification,
Version 2.1, January 2000 for the proper
resistor value. If TWI is not used, connect
to ground.
Desc: USB0 Clock/Crystal Input.
Notes: If USB is not used, connect to
ground. Active during reset.
Desc: USB0 Data –.
Notes: Pull low if not using USB. For
complete documentation of hibernate
behavior when USB is used, see the USB
chapter in the processor hardware
reference.
