Description
PB18/TIOC3B and PB19/TIOC3D
PB4/TIOC4A and PB6/TIOC4C
PB5/TIOC4B and PB7/TIOC4D
Output
The high-current pins for the MTU2 are placed in
high-impedance state when the pins
simultaneously output an active level for one or
more cycles of the peripheral clock (Pφ). (In the
case of TOCS = 0 in timer output control register 1
(TOCR1) in the MTU2, low level when the output
level select P (OLSP) bit is 0, or high level when
the OLSP bit is 1. In the case of TOCS = 1, low
level when the OLS3N, OLS3P, OLS2N, OLS2P,
OLS1N, and OLS1P bits are 0 in TOCR2, or high
level when these bits are 1.)
This active level comparison is done when the
MTU2 output function or general output function is
selected in the pin function controller. If another
function is selected, the output level is not
checked.
Pin combinations for output comparison and high-
impedance control can be selected by POE2
registers.
PB21/TIOC3BS and PB20/TIOC3DS Output
PB12/TIOC4AS and PB10/TIOC4CS
PB13/TIOC4BS and PB11/TIOC4DS
The high-current pins for the MTU2S are placed in
high-impedance state when the pins
simultaneously output an active level for one or
more cycles of the peripheral clock (Pφ). (In the
case of TOCS = 0 in timer output control register
1S (TOCR1S) in the MTU2S, low level when the
output level select P (OLSP) bit is 0, or high level
when the OLSP bit is 1. In the case of TOCS = 1,
low level when the OLS3N, OLS3P, OLS2N,
OLS2P, OLS1N, and OLS1P bits are 0 in
TOCR2S, or high level when these bits are 1.)
This active level comparison is done when the
MTU2S output function or general output function
is selected in the pin function controller. If another
function is selected, the output level is not
checked.
Pin combinations for output comparison and high-
impedance control can be selected by POE2
registers.
