Esp32 LEDC ESP-WROOM-32

Hi. I want to write value in register LEDC_HSCHn_DUTY_REG but it impossible.
For example:

#define LEDC_HSCH0_DUTY_REG 0x3FF59008

volatile uint32_t* ledc_hsch18_duty_reg = (volatile uint32_t*) LEDC_HSCH0_DUTY_REG;

*ledc_hsch18_duty_reg = (500 << 4);


But in this register after writing, again zero. Only zero.
