WORD NAME
Mux Selection for test mode mux. If the part is in test mode, the decode of this value changes the following pins:mx_sel = 0: dpwm6, dpwm7,
dpwm8 in functional mode.
mx_sel = 1: dpwm6 = vco_out, dpwm7 = div512_out, dpwm8 = div64_clk.
mx_sel = 2: dpwm6 in functional mode, dpwm7 = clk_d4, dpwm8 = dpwm_clk.
Caution! Changing this register from its default value may result in unpredictable behavior

PWM Sync Mode Select.
PWM_SYNC_SEL = xxxxxx00: INTERNAL ONLY. DPWM frequency set by an internal oscillator. External DPWM_SYNC is
ignored.
PWM_SYNC_SEL = xxxxxx01: AUTOMATIC SYNC SELECT. DPWM frequency set by an external DPWM_SYNC signal if it is
present or by the internal oscillator if no external signal is present.
PWM_SYNC_SEL = xxxxxx10: EXTERNAL ONLY. DPWM frequency set by an external signal at DPWM_SYNC. No signal at
DPWM_SYNC results in no DPWM output switching.
Bypass PLL bit = 1 forces DPWM frequency to an internal oscillator.
Charge Pump Bit1. See Plan 9 CDR Document for description.
Charge Pump Bit0. See Plan 9 CDR Document for description.
