9.3.2
PWDR are 8-bit readable/writable registers. The PWM has sixteen PWM data registers. Each
PWDR specifies the duty cycle of the basic pulse to be output, and the number of additional
pulses. The value set in PWDR corresponds to a 0 or 1 ratio in the conversion period. The upper
four bits specify the duty cycle of the basic pulse as 0/16 to 15/16 with a resolution of 1/16. The
lower four bits specify how many extra pulses are to be added within the conversion period
comprising 16 basic pulses. Thus, a specification of 0/256 to 255/256 is possible for 0/1 ratios
within the conversion period. For 256/256 (100%) output, port output should be used.
