Table 6-1 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 divid-
The divider is not cleared by the program; therefore, only the first interrupt may be generated ahead of the
