10.2
Table 10.1 lists the CPG pins and their functions.
Table 10.1 Clock Pulse Generator Pins and Functions
10.3
Table 10.2 shows the relationship between the mode control pin (MD2 to MD0) combinations and
the clock operating modes. Table 10.3 shows the usable frequency ranges in the clock operating
modes and frequency ranges of the input clock (crystal oscillation). Operation cannot be
guaranteed if settings other than those listed in table 10.3 are used.
