SYST_CSR (CSR)

SysTick Control and Status Register
address_offset : 0x0 Bytes (0x0)
access : read-write
reset_value : 0x0
reset_Mask : 0x0

ENABLE : Enables SysTick counter.
bits : 0 - 0 (1 bit)
access : read-write

Enumeration:

#0 : 0

SysTick counter Disabled

#1 : 1

SysTick counter Enabled

End of enumeration elements list.

TICKINT : Enables SysTick exception request.
bits : 1 - 1 (1 bit)
access : read-write

Enumeration:

#0 : 0

Counting down to zero does not assert the SysTick exception request

#1 : 1

Counting down to zero to asserts the SysTick exception request

End of enumeration elements list.

COUNTFLAG : SysTick flag.\nCOUNTFLAG is set when the counter transitions to zero.\nCOUNTFLAG is cleared by a read from this register or a write to the SYST_CVR.
bits : 16 - 16 (1 bit)
access : read-write


SYST_RVR (RVR)

SysTick Reload Value Register
address_offset : 0x4 Bytes (0x0)
access : read-write
reset_value : 0x0
reset_Mask : 0x0

SYST_RVR SYST_RVR read-write 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Resets to Resets to 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 RELOAD

RELOAD : Value to load into the SYST_CVR when the counter is enabled and when it reaches 0.
bits : 0 - 23 (24 bit)
access : read-write


SYST_CVR (CVR)

SysTick Current Value Register
address_offset : 0x8 Bytes (0x0)
access : read-write
reset_value : 0x0
reset_Mask : 0x0

SYST_CVR SYST_CVR read-write 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Resets to Resets to 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 CURRENT

CURRENT : Reads return the current value of the SysTick counter. A write of any value clears the field to 0, and also clears the COUNTFLAG bit to 0.
bits : 0 - 23 (24 bit)
access : read-write
