I can't help, but have to ask why you need to transmit the same code from 6 different pins?
thanks ardy_guy for response,
my project is make equipment to test device that have IR-Module for controlling device function.
the reason is,
IR-Module test is start not only at the same time with different place for device ( it's 4 different place for 4 same device ), so i need to use and control other PWM pin for transmit for 3 other place for device test.
