RTC Control Register
SWR | Software Reset 0 (0): No effect. 1 (1): Resets all RTC registers except for the SWR bit . The SWR bit is cleared by POR and by software explicitly clearing it. |
WPE | Wakeup Pin Enable 0 (0): Wakeup pin is disabled. 1 (1): Wakeup pin is enabled and wakeup pin asserts if the RTC interrupt asserts or the wakeup pin is turned on. |
SUP | Supervisor Access 0 (0): Non-supervisor mode write accesses are not supported and generate a bus error. 1 (1): Non-supervisor mode write accesses are supported. |
UM | Update Mode 0 (0): Registers cannot be written when locked. 1 (1): Registers can be written when locked under limited conditions. |
WPS | Wakeup Pin Select 0 (0): Wakeup pin asserts (active low, open drain) if the RTC interrupt asserts or the wakeup pin is turned on. 1 (1): Wakeup pin instead outputs the RTC 32kHz clock, provided the wakeup pin is turned on and the 32kHz clock is output to other peripherals. |
CPS | Clock Pin Select 0 (0): The prescaler output clock (as configured by TSIC) is output on RTC_CLKOUT. 1 (1): The RTC 32kHz crystal clock is output on RTC_CLKOUT. |
LPOS | LPO Select 0 (0): RTC prescaler increments using 32kHz crystal. 1 (1): RTC prescaler increments using 1kHz LPO, bits [4:0] of the prescaler are bypassed. |
OSCE | Oscillator Enable 0 (0): 32.768 kHz oscillator is disabled. 1 (1): 32.768 kHz oscillator is enabled. After setting this bit, wait the oscillator startup time before enabling the time counter to allow the 32.768 kHz clock time to stabilize. |
CLKO | Clock Output 0 (0): The 32 kHz clock is output to other peripherals. 1 (1): The 32 kHz clock is not output to other peripherals. |
SC16P | Oscillator 16pF Load Configure 0 (0): Disable the load. 1 (1): Enable the additional load. |
SC8P | Oscillator 8pF Load Configure 0 (0): Disable the load. 1 (1): Enable the additional load. |
SC4P | Oscillator 4pF Load Configure 0 (0): Disable the load. 1 (1): Enable the additional load. |
SC2P | Oscillator 2pF Load Configure 0 (0): Disable the load. 1 (1): Enable the additional load. |
CPE | Clock Pin Enable 0 (00): RTC_CLKOUT is disabled. 1 (01): RTC_CLKOUT is enabled on pin PTE0. 2 (10): RTC_CLKOUT is enabled on pin PTE26. |
