• Bits 2–0—Output Phase Switch 2–0 (WF, VF, UF): These bits set the positive phase/negative
phase output phase on or off state. The setting of these bits is valid only when the FB bit in this
register is set to 1. In this case, the setting of bits 2–0 is a substitute for external input.

12.2.13 Timer Subcounter (TCNTS)
The timer subcounter (TCNTS) is a 16-bit read-only counter that is used only in complementary
PWM mode. The TCNTS counter is initialized to H'00 by a power-on reset or in standby mode.
Manual reset does not initialize TCNTS. Accessing the TCNTS counter in 8-bit units is
prohibited. Always access in 16-bit units.
