Description
Reserved
These bits are always read as 0. It should not be set to 0.
Timer Reset Input Select*
Selects an external reset input when the CCLR1 and
CCLR0 bits in TCR are B'11.
0: Cleared at rising edge of the external reset
1: Cleared when the external reset is high
Reserved
This bit is always read as 0. It should not be set to 0.
Internal Clock Select 1 and 0
These bits in combination with bits CKS2 to CKS0 in TCR
select the internal clock. See table 16.2.
