Description
Initial State
P0.0
[0]
0 = Schmitt input mode, capture (TCAP0), or clock (TCLK0)
input for Timer 0. If the timer mode is configured as capture
mode or external timer clock mode, this pin will be used as
TCAP0 or TCLK0. If the timer is disabled or use the internal
clock as timer input clock, this pin will be configured as input
port.
1 = C-MOS push-pull output
0
P0.1
[1]
0 = Schmitt input mode, capture (TCAP1), or clock (TCLK1)
input for Timer 1. If the timer mode is configured as Capture
mode or external timer clock mode, this pin will be used as
TCAP1 or TCLK1. If the timer is disabled or use the internal
clock as timer input clock, this pin will be configured as input
port.
1 = C-MOS push-pull output
0
P0.2
[2]
0 = Schmitt input mode, capture (TCAP2), or clock (TCLK2)
input for Timer 2. If the timer mode is configured as Capture
mode or external timer clock mode, this pin will be used as
TCAP2 or TCLK2. If the timer is disabled or use the internal
clock as timer input clock, this pin will be configured as input
port.
1 = C-MOS push-pull output
0
P0.3
[3]
0 = Schmitt input mode or clock (TCLK3) input for Timer 3. If the
timer mode is configured as external timer clock mode, this pin
will be used as TCLK3. If the timer is disabled or use the internal
clock as timer input clock, this pin will be configured as input
port.
1 = C-MOS push-pull output
0
P0.4
[4]
0 = Schmitt input mode or clock (TCLK4) input for Timer 4. If the
timer mode is configured as external timer clock mode, this pin
will be used as TCLK4. If the timer is disabled or use the internal
clock as timer input clock, this pin will be configured as input
port.
1 = C-MOS push-pull output
