13.2.5 Output Unit
Each capture/compare block contains an output unit. The output unit is used to generate output signals
such as PWM signals. Each output unit has eight operating modes that generate signals based on the
EQU0 and EQUx signals. The TBOUTH pin function can be used to put all Timer_B outputs into a high-
impedance state. When the TBOUTH pin function is selected for the pin, and when the pin is pulled high,
all Timer_B outputs are in a high-impedance state.
13.2.5.1 Output Modes
The output modes are defined by the OUTMODx bits and are described in Table 13-4. The OUTx signal is
changed with the rising edge of the timer clock for all modes except mode 0. Output modes 2, 3, 6, and 7
are not useful for output unit 0 because EQUx = EQU0.
Table 13-4. Output Modes
OUTMODx Mode Description
The output signal OUTx is defined by the OUTx bit. The OUTx signal updates immediately when
000 Output
OUTx is updated.
The output is set when the timer counts to the TBCLx value. It remains set until a reset of the
001 Set
timer, or until another output mode is selected and affects the output.
The output is toggled when the timer counts to the TBCLx value. It is reset when the timer
010 Toggle/Reset
counts to the TBCL0 value.
The output is set when the timer counts to the TBCLx value. It is reset when the timer counts to
011 Set/Reset
the TBCL0 value.
The output is toggled when the timer counts to the TBCLx value. The output period is double the
100 Toggle
timer period.
The output is reset when the timer counts to the TBCLx value. It remains reset until another
101 Reset
output mode is selected and affects the output.
The output is toggled when the timer counts to the TBCLx value. It is set when the timer counts
110 Toggle/Set
to the TBCL0 value.
The output is reset when the timer counts to the TBCLx value. It is set when the timer counts to
111 Reset/Set
the TBCL0 value.
