size : 0x10 byte (0x0)
mem_usage : registers
protection : not protected
Self wake-up timer control register.
address_offset : 0x0 Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
CLKSEL : Select the self wake-up timer clock source. Remark: This bit only has an effect if the SEL_EXTCLK bit is not set.
bits : 0 - 0 (1 bit)
access : read-write
Enumeration:
0 : DIVIDED_IRC_CLOCK
Divided IRC clock. This clock runs at 750 kHz and provides time-out periods of up to approximately 95 minutes in 1.33 us increments. Remark: This clock is not available in not available in Deep-sleep, power-down, deep power-down modes. Do not select this option if the timer is to be used to wake up from one of these modes.
0x1 : LOW_POWER_CLOCK
This is the (nominally) 10 kHz clock and provides time-out periods of up to approximately 119 hours in 100 us increments. The accuracy of this clock is limited to +/- 40 % over temperature and processing. Remark: This clock is available in all power modes. Prior to use, the low-power oscillator must be enabled. The oscillator must also be set to remain active in Deep power-down if needed.
End of enumeration elements list.
ALARMFLAG : Wake-up or alarm timer flag.
bits : 1 - 1 (1 bit)
access : read-write
Enumeration:
0 : NO_TIME_OUT
No time-out. The self wake-up timer has not timed out. Writing a 0 to has no effect.
0x1 : TIME_OUT
Time-out. The self wake-up timer has timed out. This flag generates an interrupt request which can wake up the part from any reduced power mode including Deep power-down if the clock source is the low power oscillator. Writing a 1 clears this status bit.
End of enumeration elements list.
CLEARCTR : Clears the self wake-up timer.
bits : 2 - 2 (1 bit)
access : read-write
Enumeration:
0 : NO_EFFECT
No effect. Reading this bit always returns 0.
0x1 : CLEAR_THE_COUNTER
Clear the counter. Counting is halted until a new count value is loaded.
End of enumeration elements list.
SEL_EXTCLK : Select external or internal clock source for the self wake-up timer. The internal clock source is selected by the CLKSEL bit in this register if SET_EXTCLK is set to internal.
bits : 3 - 3 (1 bit)
access : read-write
Enumeration:
0 : INTERNAL
Internal. The clock source is the internal clock selected by the CLKSEL bit.
0x1 : EXTERNAL
External. The self wake-up timer uses the external WKTCLKIN pin.
End of enumeration elements list.
Counter register.
address_offset : 0xC Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
VALUE : A write to this register pre-loads start count value into the timer and starts the count-down sequence. A read reflects the current value of the timer.
bits : 0 - 31 (32 bit)
access : read-write
