7.1 Time Base Timer
Example :Set the time base timer frequency to fc/2
7.1.3 Function
Note 2: The interrupt frequency (TBTCK) must be selected with the time base timer disabled (TBTEN="0"). (The interrupt fre-
output of the timing generator which is selected by TBTCK. ) after time base timer has been enabled.
interrupt period ( Figure 7-2 ).
Table 7-1 Time Base Timer Interrupt Frequency ( Example : fc = 16.0 MHz, fs = 32.768 kHz )
An INTTBT ( Time Base Timer Interrupt ) is generated on the first falling edge of source clock ( The divider
The divider is not cleared by the program; therefore, only the first interrupt may be generated ahead of the set
quency must not be changed with the disable from the enable state.) Both frequency selection and enabling can be per-
formed simultaneously.
