16-bit reload register value

R(Note 1)

Note 1: These registers are protected against write during measure input mode.

Note: • These registers 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 -1" is reloaded into the counter synchronously with the count clock at the

following timing:

• At the next cycle 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

• At the next cycle when the counter is enabled in single-shot output mode

• At the next cycle when the counter underflowed in delayed single-shot output or continuous output mode

• At the next cycle when the counter is enabled in PWM output mode and at the next cyclewhen 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 the register is used as a measure register, the counter value is latched into that measure register by event input.
