Previously, when "length = 0" as failsafe, "return 0" is executed.
But we changed so that only START bit and STOP bit are executed same as other devices.
Until now, when the frequency function of CAN driver was executed, signal no output, and the frequency could not be changed.
Since there was an error in the frequency changing procedure I modified it.
Bugs are as below.
- In the case of MTU2 mode, modify a problem that does not excute "pwmout_write ()" at the end of "pwmout_pulsewidth_us ()" function.
- In the case of MTU2 mode in "pwmout_period_us ()" function, modify a problem that the executing result of "set_mtu2_duty_again ()" function does not reflect in the register of TGRA_MATCH [] and TGRC_MATCH [].
