Note: • This register must always be accessed in halfwords.
During PWM output and single-shot PWM output modes, TOU operates as a 16-bit timer. Use the reload 0
register to set the 16-bit value to be loaded into the counter when it is enabled.
The content of the reload 0 register is loaded into the counter in the following cases:
• When the counter is enabled
• When the count value set in the reload 1 register has underflowed in PWM 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.
If the value 'FFFF' is set in the reload register, F/F output will not be inverted, making it possible to produce a 0%
or 100% duty-cycle PWM output. For details, see Section 10.8.17, "0% or 100% Duty-Cycle Wave Output during
PWM Output and Single-shot PWM Output Modes."
During single-shot output, delayed single-shot output and continuous output modes, the reload 0 and reload 1
registers are combined for use as a 24-bit reload register. For details, see Section 10.8.6, Paragraph (1), "TOU
reload registers during single-shot output, delayed single-shot output and continuous output modes."
