This LSI includes an on-chip 32-bit timer unit (TMU), which has six channels (channels 0 to 5).
18.1
The TMU has the following features.
• Auto-reload type 32-bit down-counter provided for each channel
• Input capture function provided only for channel 2
• Selection of rising edge or falling edge as external clock input edge when external clock is
• 32-bit timer constant register for auto-reload use, readable/writable at any time, and 32-bit
• Selection of six counter input clocks: Channels 0 to 2
• Selection of five counter input clocks: Channels 3 to 5
• Two interrupt sources
selected or input capture function is used: Channels 0 to 2
down-counter provided for each channel
External clock (TCLK) and five internal clocks (Pck/4, Pck/16, Pck/64, Pck/256, and
Pck/1024) obtained by dividing the peripheral clock (Pck is the peripheral clock).
Five internal clocks (Pck/4, Pck/16, Pck/64, Pck/256, and Pck/1024) (Pck is the peripheral
clock).
One underflow source (each channel) and one input capture source (channel 2).
