16 bits PPG
The PPG timer consists of the following:
Prescaler
16-bit down-counter: 1
16-bit data register with a cycle setting buffer
16-bit compare register with a duty setting buffer
Pin control unit
The PPG timer can output pulses synchronized to the software trigger.
The output pulse can be changed to any cycle and duty freely by updating the PCSRL, PCSRH/PDUTL, PDUTH
registers.
PWM function
The PPG timer can output pulses programmably by updating the PCSR and PDUT registers described above
in synchronization to the trigger.
Can also be used as a D/A converter by an external circuit.
Single shot function
By detecting an edge of the trigger input, a single pulse can be output.
16-bit down counter
The counter operation clock comes from eight kinds optional. There are eight kinds of internal clocks.
(
φ, φ2, φ4, φ8, φ16, φ32, φ64, φ128) φ : machine clock
The counter can be initialized to “FFFFH” at a reset or counter borrow.
Interrupt request
The PPG timer generates an interrupt request when :
Timer start-up
Counter borrow occurrence (cycle match)
Duty match occurrence
