RTC_COMP_LSB_REG Address Offset 0x13 Physical Address Instance (RESET DOMAIN: FULL RESET) Description RTC compensation register (LSB) Notes: This register must be written in 2-complement. This means that to add one 32-kHz oscillator period every hour, microcontroller needs to write FFFF into RTC_COMP_MSB_REG and RTC_COMP_LSB_REG. To remove one 32-kHz oscillator period every hour, microcontroller needs to write 0001 into RTC_COMP_MSB_REG and RTC_COMP_LSB_REG. The 7FFF value is forbidden. Type RW 7 6 5 4 3 2 1 0 RTC_COMP_LSB Bits Field Name Description Type Reset 7:0 RTC_COMP_LSB This register contains the number of 32-kHz periods to be added into the 32-kHz counter every hour [LSB] RW 0x00 Table 6-24. RTC_COMP_MSB_REG Address Offset 0x14 Physical Address Instance (RESET DOMAIN: FULL RESET) Description RTC compensation register (MSB) Notes: See RTC_COMP_LSB_REG Notes. Type RW 7 6 5 4 3 2 1 0 RTC_COMP_MSB Bits Field Name Description Type Reset 7:0 RTC_COMP_MSB This register contains the number of 32-kHz periods to be added into the 32-kHz counter every hour [MSB] RW 0x00 Table 6-25. RTC_RES_PROG_REG Address Offset 0x15 Physical Address Instance (RESET DOMAIN: FULL RESET) Description RTC register containing oscillator resistance value Type RW 7 6 5 4 3 2 1 0 Reserved SW_RES_PROG Bits Field Name Description Type Reset 7:6 Reserved Reserved bit RO R returns 0s 0x0 5:0 SW_RES_PROG Value of the oscillator resistance RW 0x27 Table 6-26. RTC_RESET_STATUS_REG Address Offset 0x16 Physical Address Instance (RESET DOMAIN: FULL RESET) Description RTC register for reset status |
