SysTick Reload Value Register (STRELOAD)
NOTE
This register can only be accessed from privileged mode.
The STRELOAD register specifies the start value to load into the SysTick Current Value (STCURRENT) register when the counter reaches 0. The start value can be between 0x1 and 0x00FFFFFF. A start value of 0 is possible but has no effect because the SysTick interrupt and the COUNT bit are activated when counting from 1 to 0.
SysTick can be configured as a multi-shot timer, repeated over and over, firing every N+1 clock pulses, where N is any value from 1 to 0x00FFFFFF. For example, if a tick interrupt is required every 100 clock pulses, 99 must be written into the RELOAD field.
Note that in order to access this register correctly, the system clock must be faster than 8 MHz.
STRELOAD is shown in Figure 2-4 and described in Table 2-12.
