10.6 TML (Input-Related 32-Bit Timer)
10.6.1 Outline of TML
TML (Timer Measure Large) is an input-related 32-bit timer capable of measuring input pulses in two circuit
blocks comprising a total of eight channels.
The table below shows specifications of TML. The diagram in the next page shows a block diagram of TML.
Table 10.6.1 Specifications of TML (Input-Related 32-Bit Timer)
Item Specification
Number of channels 8 channels (2 circuit blocks consisting of 4 channels each, 8 channels in total)
Input clock BCLK/2 (10.0 MHz when f(BCLK) = 20 MHz) or clock bus 1 input
Counter 32-bit up-counter × 2
Measure register 32-bit measure register × 8
Timer startup Start counting immediately after reset
