TMR1 : Timer mode register 1
TMR2 : Timer mode register 2
TM3EL : Timer 3 count source
switch bit (address 00C7 16)
CM : CPU mode register
Notes 1: “H” pulse width of external clock inputs TIM2 and TIM3 needs 4 machine cycles or more.
2: When the external clock source is selected, timers 1, 2, and 3 are counted at a rising edge of input signal.
FF16
