16-Bit High-Precision Igbt Output (With Variable Period/Duty; Operation - Panasonic MN101L Series User Manual

9.10 16-bit High-Precision IGBT Output
(with Variable Period/Duty)
The high-precision IGBT signal is output from TM7IO or TM8IO pin while the timer starts counting up using the
external interrupt input signal as a trigger. A trigger of the high-precision IGBT output can be selected from
IRQ0, 1, 2 or Timer 7 count operation. After starting the count operation, the other operation is the same as that of
the 16-bit high-precision PWM output
Updating the Timer 7 preset register 1 and 2 is prohibited during IGBT operation.

Operation

IGBT Trigger
IGBT trigger can be selected from IRQ0, 1, 2 and Timer 7 count operation by setting the TM7MD3.TM7IGBT0-
1. The IGBT output starts by detecting the trigger input level.
When setting the TM7MD3.T7IGBTTR to "1" to select the rising edge, the count operation is executed while the
corresponding interrupt pin is "High". When setting the TM7MD3.T7IGBTTR to "0" to select the falling edge,
the count operation is executed while the corresponding interrupt pin is "Low".
To control the activation with the instruction, select "TM7EN count operation". In that case, the timer count oper-
ation and IGBT output are controlled with the TM7MD1.TM7EN. When setting the bit to "1" to start counting,
the count operation continues until the bit is set to "0" to stop counting. Be sure to set the TM7MD3.T7IGBT0-1
before setting the TM7MD1.TM7EN. In this case, The setting of TM7MD3.T7IGBTTR is invalid. When the
counter is stopped, the binary counter is cleared at the same time. The data of the preset register are loaded to the
compare register in synchronization with the count clock.
