Registers
In the TPM v3 a write to TPMxSC register in BDM mode clears the write coherency mechanism
of TPMxMODH:L registers. Instead, in the TPM v2 this coherency mechanism is not cleared when
there is a write to TPMxSC register.
In the TPM v3 if CLKSB:CLKSA = 00, then the EPWM signal in the channel output is not update
(it is frozen while CLKSB:CLKSA = 00). Instead, in the TPM v2 the EPWM signal is updated at
the next rising edge of bus clock after a write to TPMxCnSC register.
The
after the reset (CLKSB:CLKSA = 00) and if there is a write to TPMxCnSC register.
BUS CLOCK
In this case, the TPM v3 waits for the start of a new PWM period to begin using the new duty
cycle setting. Instead, the TPM v2 changes the channel output at the middle of the current
PWM period (when the count reaches 0x0000).
In this case, the TPM v3 finishes the current PWM period using the old duty cycle setting.
Instead, the TPM v2 finishes the current PWM period using the new duty cycle setting.
