12.2 16-bit Timer / Counter Mode
The Timer register is being run with 16 bits. A 16-bit timer/
counter register T0, T1 are increased from 0000
H
until it
matches TDR0, TDR1 and then resets to 0000
H
. The
match output generates Timer 0 interrupt not Timer 1 in-
terrupt.
The clock source of the Timer 0 is selected either internal
or external clock by bit T0CK[2:0].
In 16-bit mode, the bits T1CK[1:0] and 16BIT of TM1
should be set to "1" respectively.
