+The specific addresses will be different on different ESP32
+models. For example, ESP32-S3 uses these values:

+ DR_REG_DPORT_BASE = const(0x600C_0000)
+ DPORT_PERIP_CLK_EN0_REG = const(DR_REG_DPORT_BASE + 0x0018)
+ DPORT_PERIP_RST_EN0_REG = const(DR_REG_DPORT_BASE + 0x0020)
+ DPORT_PWM0_CLK_EN = const(1 << 17)
+ MCPWM0 = const(0x6001_E000 + 0x0004)
+ ...

Note that before a peripheral can be used its clock must be enabled and it must
be taken out of reset. In the above example the following registers are used
for this:
