The TOCR is an 8-bit read/write register which works to select input capture signals and output
comparing output level, to permit output comparing outputs and to control switching over of the
access of the OCRA and OCRB. See the section 17.2.4 Timer Interrupt Enabling Register
(TIER) regarding the input capture inputs A.
The TOCR is initialized to H'00 when reset or under the standby mode, watch mode, subsleep
mode, module stop mode or subactive mode.
Bit 7: Selecting the Input Capture B Signals (ICSB)
This bit works to select the input capture B signals.
Bit 7
ICSB Description
0 Selects the FTIB pin for inputting of the input capture B signals
1 Selects the VD as the input capture B signals
Bit 6: Selecting the Input Capture C Signals (ICSC)
This bit works to select the input capture C signals. The DVCTL is the edge detecting pulse
selected by the CTL dividing timer.
Bit 6
ICSC Description
0 Selects the FTIC pin for inputting of the input capture C signals
1 Selects the DVCTL as the input capture C signals
Bit 5: Selecting the Input Capture D Signals (ICSD)
This bit works to select the input capture D signals.
Bit 5
ICSD Description
0 Selects the FTID pin for inputting of the input capture D signals
1 Selects the NHSW as the input capture D signals
