Reads to reserved registers or bits will return a value of 0.
Software must not attempt locks to the memory-mapped I/O ranges for High Precision
conditions may occur.
Event Timers. If attempted, the lock is not honored, which means potential deadlock
Main Counter Tick Period (COUNTER_CLK_PER_CAP) — RO. This field indicates the
period at which the counter increments in femptoseconds (10^-15 seconds). This will
return 0429B17F when read. This indicates a period of 69841279 fs (69.841279 ns).
Vendor ID Capability (VENDOR_ID_CAP) — RO. This is a 16-bit value assigned to
Intel.
Replacement Interrupt Rout option is supported.
Reserved. This bit returns 0 when read.
Counter Size Capability (COUNT_SIZE_CAP) — RO. Hardwired to 1. Counter is 64-bit
wide.
Number of Timer Capability (NUM_TIM_CAP) — RO. This field indicates the number of
timers in this block.
02h = Three timers.
Revision Identification (REV_ID) — RO. This indicates which revision of the function is
implemented. Default value will be 01h.
Legacy Replacement Rout Capable (LEG_RT_CAP) — RO. Hardwired to 1. Legacy
