Note: This register must always be accessed in halfwords.
The TOP reload registers are used to load data into the TOP counter registers (TOP0CT-
TOP10CT). It is in the following cases that the content of the reload register is loaded in the counter:
• When the counter is enabled in single-shot mode
• When the counter underflowed in delayed single-shot or continuous mode
Writing data to the reload register does not mean that the data is loaded into the counter
simultaneously.
Note that data reloading after an underflow is performed synchronously with the clock period in
which the counter underflowed.
