59 * To get the value from the Global Timer Counter register proceed as follows:
60 * 1. Read the upper 32-bit timer counter register
61 * 2. Read the lower 32-bit timer counter register
62 * 3. Read the upper 32-bit timer counter register again. If the value is
63 * different to the 32-bit upper value read previously, go back to step 2.
64 * Otherwise the 64-bit timer counter value is correct.
93 * 1. Clear the Comp Enable bit in the Timer Control Register.
94 * 2. Write the lower 32-bit Comparator Value Register.
95 * 3. Write the upper 32-bit Comparator Value Register.
