(5) Waveform Generator module
The waveform generator consists of three 16-bit timer registers, three timer control registers and 16-bit waveform
control register.
With waveform generator, it is possible to generate real time output, 16-bit PPG waveform output, non-overlap
3-phase waveform output for inverter control and DC chopper waveform output.
It is possible to generate a non-overlap waveform output based on dead-time of 16-bit timer. (Dead-time timer
function)
It is possible to generate a non-overlap waveform output when realtime output is operated in 2-channel mode.
(Dead-time timer function)
By detecting realtime output compare match, GATE signal of the PPG timer operation will be generated to
start or stop PPG timer operation. (GATE function)
When a match is detected by realtime output compare, the 16-bit timer is activated. The PPG timer can be
started or stopped easily by generating a GATE signal for PPG operation until the 16-bit timer stops. (GATE
function)
Forced to stop output waveform using DTTI0 pin input
Interrupt generated when DTTI0 active or 16-bit tmer underflow
EI2OS supported
MCU to 3-phase Motor Interface Circuit
RTO0 (U) , RTO2 (V) , RTO4 (W) are called “UPPER ARM”.
RTO1 (X) , RTO3 (Y) , RTO5 (Z) are called “LOWER ARM”.
RTO0 (U) and RTO1 (X) are called “non-overlapping output pair”.
RTO2 (V) and RTO3 (Y) are called “non-overlapping output pair”.
RTO4 (W) and RTO5 (Z) are called “non-overlapping output pair”.
(U) , (V) , (W) are the 3-phase coil connection.
