TOP0RL–TOP10RL
16-bit reload register value
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). The
content of the reload register is loaded into the counter in the following cases:
• When the counter is enabled in single-shot output mode
• When the counter underflowed in delayed single-shot or continuous output mode
Simply because data is written to the reload register does not mean that the data is loaded into the counter. The
counter is loaded with data in only the above cases.
Note that reloading of data after an underflow is performed synchronously with a clock pulse at which the
counter underflowed.
