DS40001609C-page 271 PIC16(L)F1508/9 24.0 CONFIGURABLE LOGIC CELL (CLC) The Configurable Logic Cell (CLCx) provides program- mable logic that operates outside the speed limitations of software execution. The logic cell takes up to 16 input signals, and through the use of configurable gates, reduces the 16 inputs to four logic lines that drive one of eight selectable single-output logic func- tions. Input sources are a combination of the following: • I/O pins • Internal clocks • Peripherals • Register bits The output can be directed internally to peripherals and to an output pin. Refer to Figure 24-1 for a simplified diagram showing signal flow through the CLCx. Possible configurations include: • Combinatorial Logic -AND -NAND - AND-OR - AND-OR-INVERT -OR-XOR -OR-XNOR • Latches -S-R - Clocked D with Set and Reset - Transparent D with Set and Reset - Clocked J-K with Reset FIGURE 24-1: DIGITAL-TO-ANALOG CONVERTER BLOCK DIAGRAM Logic Function (2) lcxg2 lcxg1 lcxg3 lcxg4 LCxMODE<2:0> lcxq LCxEN LCx_in[0] LCx_in[1] LCx_in[2] LCx_in[3] LCx_in[4] LCx_in[5] LCx_in[6] LCx_in[7] LCx_in[8] LCx_in[9] LCx_in[10] LCx_in[11] LCx_in[12] LCx_in[13] LCx_in[14] LCx_in[15] LCxPOL det Interrupt det Interrupt set bit CLCxIF LCXINTN LCXINTP LCxOE TRIS Control CLCx to Peripherals Q1 LCx_out LCxOUT MLCxOUT DQ Rev. 10-000025A 8/1/2013 Note 1: See Figure 24-2. 2: See Figure 24-3. |
