The OEBCR register is used to select the timer (TOP or TIO) whose underflow signal is supplied to the output
event bus.
10.2.4 Input Processing Control Unit
The Input Processing Control Unit processes TCLK and TIN input signals to the MJT. In TCLK input processing,
it selects the source of TCLK signal, and for external input, it selects the active edge (rising or falling or both) or
level (high or low) of the signal, at which to generate the clock signal supplied to the clock bus.
In TIN input processing, the unit selects the active edge (rising or falling or both) or level (high or low) of the
signal, at which to generate the enable, measure or count source signal for each timer or the signal supplied to
each event bus.
Following input processing registers are included:
• TLCK Input Processing Control Register (TCLKCR)
• TIN0–4 Input Processing Control Register (TIN04CR)
• TIN5–8 Input Processing Control Register (TIN58CR)
• TIN9–11 Input Processing Control Register (TIN911CR)
• TIN12–19 Input Processing Control Register (TIN1219CR)
• TIN20–23, TIN30–33 Input Processing Control Register (TIN2023_3033CR)
• TIN24,25 Input Processing Control Register (TIN2425CR)
• TIN26,27 Input Processing Control Register (TIN2627CR)
• TIN28,29 Input Processing Control Register (TIN2829CR)
