MULTIJUNCTION TIMERS
10.8 TOU (Output-Related 24-Bit Timer)
32180 Group User’s Manual (Rev.1.0)
During single-shot output, delayed single-shot output and continuous output modes, TOU operates as a 24-bit
timer. The value set in the 24 low-order bits of the reload register is loaded into the counter. Bits 8–15 and bits
16–31 are the 8 high-order and the 16 low-order bits of the counter, respectively. Bits 0–7 are ignored.
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 has underflowed in delayed single-shot output 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.
During PWM output and single-shot PWM output modes, the TOU reload register operates as 16-bit reload 0
and reload 1 registers. For details, see Section 10.8.6, Paragraph (2), “TOU reload registers during PWM output
and single-shot PWM output modes.”
