21 / 77 page  CCU 3000, CCU 3000-I CCU 3001, CCU 3001-I MICRONAS INTERMETALL 21 2.15. IR-Input The IR-interface consists of two parallel edge detectors which trigger the rising and falling edge. The respective state of the rising edge triggered flip-flop can be read from D0 (triggered positively), or D1 (triggered nega- tively). Any read event via the CPU deletes both flip- flops. D2 reflects the status of the IR pin, D3 to D7 are set to 0. If the CPU is switched off, the IR-Interface is no longer available, as the IR pin is used as output for the interrupt controller. For use as an emulator this function has to be rebuilt externally. The I/O-address designed for the IR- INPUT is treated as an external address when the CPU is switched off, so that the software can remain un- touched.

Mask Options There are two mask options: OSC option: if this option is set, X1 and X2 can be used as clock input and output or as XTAL pins, (depending on control word bit 5) RES option: if this option is set, the reset sources Power on and Clock Supervision are disabled with bit 0 of the test register 2FFH. Default = enabled). In the production version none of the options is set, in the EMU version both are set. |
