Function
Table 9-1 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
performed simultaneously.
