mode:
A. Writes to this register load the value against which the
main counter will be compared for this timer.
B. When the main counter equals the value last written to
this register, the corresponding interrupt will be generated
(when enabled).
C. The value in this register does not change based on the
interrupt being generated.
A. When the main counter equals the value last written to
this register, the corresponding interrupt will be generated
(when enabled).
B. After the main counter equals the value in this register,
the value in this register is increased by the value last
written to the register.
For example, if the value written to the register is
00000123h, then:
1. An interrupt will be generated when the main counter
reaches 00000123h.
2. The value in this register will be adjusted by the
hardware to 00000246h.
3. Another interrupt will be generated when the main
counter reaches 00000246h.
4. The value in this register will be adjusted by the
hardware to 00000369h.
C. As each periodic interrupt occurs, the value in this
register will increment. When the incremented value is
greater than the maximum value possible for this register
(FFFFFFFFh for a 32-bit timer or FFFFFFFFFFFFFFFFh for a
64-bit timer), the value will wrap around through 0. For
example, if the current value in a 32-bit timer is
FFFF0000h and the last value written to this register is
20000, then after the next interrupt the value will change
to 00010000h.
implemented. For example, a 32-bit timer will have a
default value of 00000000FFFFFFFFh. A 64-bit timer will
have a default value of FFFFFFFFFFFFFFFFh.
