When the floating-point calculation is executed into the processing which is called from IRQ handlers, VFP register is overwritten.
Therefore, we fixed the issue. we added the process to execute the saving (Push) and the returning (Pop) of VFP register in before and after the appropriate processing.
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 [].
