DIV WORD Figure 3 (MSB) (LSB) N (9-BITS) PDN This bit is used to determine the function of the PDN / SELX pin. If PDN=0, the PDN / SELX pin can be used to determine the timing reference (either the internal oscillator or an external reference/crystal). If PDN=1, the PDN /SELX pin is used to put the device into power-down mode. EN0 This bit is used to determine whether the OUT0 pin is active or not. If EN0 =1, OUT0 is disabled (High- impedance). If EN0 =0, the internal reference clock (MCLK) is output from OUT0. The OE pin has no effect on OUT0, but OUT0 is disabled as part of the power-down sequence. N These nine bits determine the value of the programmable divider. The range of divisor values is from 2 to 513, and is equal to the programmed value of N plus 2: Table 3 BIT VALUES DIVISOR (N) VALUE 000000000 2 000000001 3 .. .. .. .. .. 111111111 513 NOTE: The maximum value of N is constrained by the minimum output frequency. If the internal clock is selected, INTOSC/(M*N) must be greater than fOUTmin; if the external clock is selected, EXTCLK/N must be greater than fOUTmin . (If DIV1=1, then INTOSC or EXTCLK, as applicable, must exceed fOUTmin). |
