10 / 16 page Functional Description (Continued) IO CONFIGURATIONS COP413C outputs have the following configurations illus- trated in Figure 7 a Standard SO SK Output A CMOS push-pull buffer with an N-channel device to ground in conjunction with a P-channel device to VCC compatible with CMOS and LSTTL b Low Current G Output This is the same configuration as (a) above except that the sourcing current is much less c Standard TRI-STATE L Output L output is a CMOS out- put buffer similar to (a) which may be disabled by pro- gram control The SI and RESET inputs are Hi-Z inputs ( Figure 7d ) When using the G IO port as an input set the output regis- ter to a logic ‘‘1’’ level The P-channel device will act as a pull-up load When using the L IO port as an input disable the L drivers with the LEI instruction The drivers are then in TRI-STATE mode and can be driven externally All output drivers use one or more of three common devices numbered 1 to 3 Minimum and maximum current (IOUT and VOUT) curves are given in Figure 8 for each of these devices to allow the designer to effectively use these IO configura- tions a Standard Push-Pull Output b Low Current Push-Pull Output TLDD8537 – 7 c Standard TRI-STATE ‘‘L’’ Output d Hi-Z Input FIGURE 7 IO Configurations SO SK L Port G Port Minimum Sink Current SO SK L Port Standard Minimum Source Current G Port Low Current Minimum Source Current COP413CCOP413CH Low Current G Port Maximum Source Current COP313CCOP313CH Low Current G Port Maximum Source Current Maximum Quiescent Current TLDD8537 – 8 FIGURE 8 10 |
