Description
pwm
pwm10_df
RW
7000_2C78h [15:8]
PWM10 falling edge delay (dead)
time from t1 or t2. Mapping of the
falling edge to t1 or t2 defined by
pwm10_fall_sel. In order to
synchronously update all dead
times simultaneously, an update to
any dead time register only
becomes effective after
7000_2C80h (pwm12_dr,
pwm12_df) is written.
Computed by FW from PMBus
command as follows:
pwm10_df[7:0] =
PWM_DEADTIME[151:144]
LSB = 1.25 ns, range = 0.0 to
318.75 ns
pwm
pwm11_dr
RW
7000_2C7Ch [7:0]
PWM11 rising edge delay (dead)
time from t1 or t2. Mapping of the
rising edge to t1 or t2 defined by
pwm11_rise_sel. In order to
synchronously update all pwmX_dr
and pwmX_df times
simultaneously, an update to any
dead time register only becomes
effective after 7000_2C80h
(pwm12_dr, pwm12_df) is written.
Computed by FW from PMBus
command as follows:
pwm11_dr[7:0] =
PWM_DEADTIME[175:168]
LSB = 1.25 ns, range = 0.0 to
318.75 ns
pwm
pwm11_df
RW
7000_2C7Ch [15:8]
PWM11 falling edge delay (dead)
time from t1 or t2. Mapping of the
falling edge to t1 or t2 defined by
pwm11_fall_sel. In order to
synchronously update all dead
times simultaneously, an update to
any dead time register only
becomes effective after
7000_2C80h (pwm12_dr,
pwm12_df) is written.
Computed by FW from PMBus
command as follows:
pwm11_df[7:0] =
PWM_DEADTIME[167:160]
LSB = 1.25 ns, range = 0.0 to
318.75 ns
