* - Timer Configuration registers, e.g.: MCPWM_TIMER_SYNCI_CFG_REG, MCPWM_TIMER0_CFG0_REG, MCPWM_TIMER0_CFG1_REG, MCPWM_TIMER0_CFG1_REG
* - Operator Configuration registers, e.g.: MCPWM_OPERATOR_TIMERSEL_REG
* |- Generator Configuration registers, e.g.: MCPWM_GEN0_STMP_CFG_REG, MCPWM_GEN0_TSTMP_A_REG, MCPWM_GEN0_TSTMP_B_REG, MCPWM_GEN0_CFG0_REG, MCPWM_GEN0_FORCE_REG, MCPWM_GEN0_A_REG, MCPWM_GEN0_B_REG
* |- Dead Time Configuration registers, e.g.: MCPWM_DT0_CFG_REG, MCPWM_DT0_FED_CFG_REG, MCPWM_DT0_RED_CFG_REG
* |- Carrier Configuration registers, e.g.: MCPWM_CARRIER0_CFG_REG
* └- Fault Handle Configuration registers, e.g.: MCPWM_FAULT_DETECT_REG, MCPWM_FH0_CFG0_REG, MCPWM_FH0_CFG1_REG
