Description
SPI Serial Clock: The SPI master supplies this signal. If the F1680 Series
MCU is the SPI master, this pin is an output. If it is the SPI slave, this pin is an
input.
Master Out Slave In: This signal is the data output from the SPI master
device and the data input to the SPI slave device.
MISO
I/O Master In Slave Out: This pin is the data input to the SPI master device and
the data output from the SPI slave device.
Timers
T0OUT/T1OUT/ O
T2OUT
T0OUT/T1OUT/ O
T2OUT
T0IN/T1IN/T2IN I
Timer Output 0–2: These signals are output from the timers.
Timer Complement Output 0–2: These signals are output from the timers in
PWM DUAL OUTPUT Mode.
Timer Input 0–2: These signals are used as the capture, gating and counter
inputs. The T0IN/T1IN/T2IN signal is multiplexed with T0OUT/T1OUT/
T2OUT signals.
Multi-Channel Timers
TACHA, TACHB, I/O
TACHC, TACHD
T4IN
I
Multi-channel timer Input/Output: These signals function as Capture input or
Compare output for channels CHA, CHB, CHC and CHD.
Multi-channel Timer clock input: This signal allows external input to serve as
the clock source for the Multi-channel timer.
Comparators
C0INP/C0INN, I
C1INP/C1INN
C0OUT/C1OUT O
Comparator Inputs: These signals are positive and negative inputs to the
comparator 0 and comparator 1.
Comparator Outputs: These are the output from the comparator 0 and the
comparator 1.
Analog
ANA[7:0]
I
Analog Port: These signals are used as inputs to the ADC. The ANA0, ANA1
and ANA2 pins can also access the inputs and outputs of the integrated Low-
Power Operational Amplifier.
VREF
I/O ADC reference voltage input.
Low-Power Operational Amplifier
AMPINP/AMPINN I
Low-Power Operational Amplifier Inputs: If enabled, these pins drive the
positive and negative amplifier inputs respectively.
AMPOUT
O
Low-Power Operational Amplifier Output: If enabled, this pin is driven by the
on-chip low-power operational amplifier.
