8-bit Timer Cascade Connection
8.8.1
Operation
16-bit timers in cascade connection are the combination of the following 8-bit timers.
Timer 0 connected with Timer 1, Timer 2 connected with Timer3 , or Timer 4 connected with Timer 5 operates as
a 16-bit timer in cascade connection.
• Timer 0 connected with Timer 1
• Timer 2 connected with Timer 3
• Timer 4 connected with Timer 5
In cascade connection, the timer corresponding to lower 8 bits of the 16-bit counter is grouped into "Type Timer
0" and the timer of upper 8 bits is grouped into "Type Timer 1".
Timer 0, Timer 2, and Timer 4 are Type Timer 0. Timer 1, Timer 3, and Timer 5 are Type Timer 1.
Operation of 16-bit Timer Cascade Connection (Timer 0 connected with Timer 1, Timer 2 connected
connected with Timer 3, Timer 4 connected with Timer 5)
The timer functions in 16-bit cascade connection are listed in Table:8.8.1.
