12.3.4
OVF in TCSR is set to 1 when the timer count overflows (changes from H'FF to H'00). Figure
12.8 shows the timing of this operation.
12.3.5
If bits CKS2 to CKS0 in either TCR0 or TCR1 are set to B'100, the 8-bit timers of the two
channels are cascaded. With this configuration, a single 16-bit timer can be used (16-bit timer
mode) or compare-matches of 8-bit channel 0 can be counted by the timer of channel 1 (compare-
match count mode). In this case, the timer operates as described below.
