This LSI includes a three-channel (channel 0 to 2) 32-bit timer unit (TMU).
14.1
The TMU has the following features:
• Each channel is provided with an auto-reload 32-bit down counter
• All channels are provided with 32-bit constant registers and 32-bit down counters for an auto-
• All channels generate interrupt requests when the 32-bit down counter underflows
• Allows selection among 4 counter input clocks: Pφ/4, Pφ/16, Pφ/64, and Pφ/256
Note: Pφ is the internal clock for peripheral modules. See section 11, On-Chip Oscillation
