Buffer Type^a Description
TTL
UART module 1 Data Carrier Detect modem status
input signal.
TTL
UART module 1 Data Set Ready modem output
control line.
TTL
UART module 1 Data Terminal Ready modem
status input signal.
TTL
UART module 1 Ring Indicator modem status input
signal.
TTL
UART module 1 Request to Send modem flow
control output line.
TTL
UART module 1 receive. When in IrDA mode, this
signal has IrDA modulation.
TTL
UART module 1 transmit. When in IrDA mode, this
signal has IrDA modulation.
TTL
UART module 2 receive. When in IrDA mode, this
signal has IrDA modulation.
TTL
UART module 2 transmit. When in IrDA mode, this
signal has IrDA modulation.
Power
Power
Power source for the Hibernation module. It is
normally connected to the positive terminal of a
battery and serves as the battery
backup/Hibernation module power-source supply.
Positive supply for I/O and some logic.
Power
The positive supply for the analog circuits (ADC,
Analog Comparators, etc.). These are separated
from VDD to minimize the electrical noise contained
on VDD from affecting the analog functions. VDDA
pins must be supplied with a voltage that meets the
specification in Table 25-2 on page 1123, regardless
of system implementation.
