 Two 10-bit PWM channels, each with eight outputs.
 10-bit counter (PWCNT) and cycle register (PWCYR).
 Duty and output polarity can be set for each output.
 Each of four duty registers (PWDTR) is provided with buffer registers (PWBFR), with data
 A duty cycle of 0% to 100% can be selected by means of a duty register setting.
 There is a choice of five operating clocks (φ, φ/2, φ/4, φ/8, φ/16).
 An interrupt can be requested independently for each channel by a cycle register compare
 Block transfer and one-word data transfer are available by activating the data transfer
 IOL/IOH: 15 mA typ. and 30 mA max.
 Total IOL/IOH: 120 mA max. (target value)
transferred automatically every cycle.
