CDR3L, PWM3DRL and T3L registers share peripheral address. When PWM mode is enabled,
reading this address gives PWM3DRL. When PWM mode is disabled, reading this address gives
CDR3L in Capture Mode or T3L in Output Compare Mode. Writing this address alters PWM3DRL
when PWM3E bit is
‘1’. When PWM mode is disabled, writing this address alters T3DRL.
