Note 1: This register is protected against write during measure input mode.
Note: • This register must always be accessed in halfwords.
The TIO Reload 0/ Measure Registers serve dual purposes as a register for reloading data into the TIO Count
Registers (TIO0CT–TIO9CT) and as a measure register during measure input mode. These registers are pro-
tected against write during measure input mode.
The content of the reload 0 register is loaded into the counter in the following cases:
• When after the counter started counting in noise processing input mode, the input signal is inverted and a
valid-level signal is entered again before the counter underflows
• When the counter is enabled in single-shot output mode
• When the counter underflowed in delayed single-shot output or continuous output mode
• When the counter is enabled in PWM output mode and when the counter value set by the reload 1 register
underflowed
Simply because data is written to the reload 0 register does not mean that the data is loaded into the counter.
The counter is loaded with data in only the above cases.
If this register is used as a measure register, the counter value is latched into that measure register by event
input.
