The absolute values of the high and low widths of the input capture signal can be measured by
using timer G. The CCLR1 and CCLR0 bits of TMG should be set to 1. Figure 9.16 shows an
example of this operation.

when the pin function is switched, either by controlling the level of the input capture pin so
that it does not satisfy the conditions in tables 9.18 and 9.19, or by setting the IIEGS bit of
TMG to select the edge opposite to the falsely generated edge.

Figure 9.15 Procedure for Modifying Port Mode Register and Clearing Interrupt
Wait for TMIG to be recognized
Clear interrupt request flag to 0
Modify port mode register
Sample Timer G Application
Clear I bit to 0 in CCR
Set I bit to 1 in CCR
Figure 9.16 Sample Timer G Application
Request Flag
Disable interrupts (or disable by clearing interrupt
enable bit in interrupt enable register 2)
Modify port mode register setting, wait for TMIG
to be recognized (at least two system clocks when
noise canceling is disabled; at least five sampling
clocks when noise canceling is enabled), then
clear interrupt request flag to 0
Enable interrupts
