Pins disabled when When RDY_MOD device jumps programming mode upon falling edge (See Figure YY). signal presents this translated (card reset signal) when signal this latched when This also used programming mode (See ZZZ). This connected external microcontroller interface. bidirectional level translator adapts serial signal between smartcard microcontroller. level translator enabled when signal present this latched when This also used programming mode (See ZZZ). This pin, generally connected controller serial interface clock, used communications with synchronous cards. signal internal clock selector circuit translated CRD_CLK upon appropriate programming MC33561. When device operates programming mode, signal presents this latched when This connected either microcontroller master clock, clock signal, drive asynchronous cards. signal internal clock selector circuit translated CRD_CLK either same frequency, divided depending upon programming mode (See AAA). This activated when card been inserted detected interface. signal reset logic rising edge either PWR_ON. Collector open mode makes possible wired AND/OR external logic. When more interfaces share function with single micro controller, software must polls MC33561 identify origin interupt.
