SYST_CVR (CVR)


SYST_CSR (CSR)

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

SYST_CSR SYST_CSR 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 ENABLE TICKINT CLKSRC COUNTFLAG

ENABLE : System Tick Counter Enabled\n
bits : 0 - 0 (1 bit)
access : read-write

Enumeration:

#0 : 0

Counter Disabled

#1 : 1

Counter Enabled and will operate in a multi-shot manner

End of enumeration elements list.

TICKINT : System Tick Interrupt Enabled\n
bits : 1 - 1 (1 bit)
access : read-write

Enumeration:

#0 : 0

Counting down to 0 does not cause the SysTick exception to be pended. Software can use COUNTFLAG to determine if a count to 0 has occurred

#1 : 1

Counting down to 0 will cause the SysTick exception to be pended. Clearing the SysTick Current Value register by a register write in software will not cause SysTick to be pended

End of enumeration elements list.

CLKSRC : System Tick Clock Source Selection\n
bits : 2 - 2 (1 bit)
access : read-write

Enumeration:

#0 : 0

Clock source is optional, refer to STCLK_S

#1 : 1

Core clock used for SysTick timer

End of enumeration elements list.

COUNTFLAG : System Tick Counter Flag\nReturns 1 if timer counted to 0 since last time this register was read.\nCOUNTFLAG is set by a count transition from 1 to 0.\nCOUNTFLAG is cleared on read or by a write to the Current Value register.
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 : System Tick Reload Value\nValue to load into the Current Value register when the counter 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 : System Tick Current Value\nCurrent counter value. This is the value of the counter at the time it is sampled. The counter does not provide read-modify-write protection. The register is write-clear. A software write of any value will clear the register to 0. Unsupported bits RAZ (see SysTick Reload Value register).
bits : 0 - 23 (24 bit)
access : read-write
