Function
+5V power supply
Switches CDI input to either synchronous mode (1 : 1) “L” or asynchronous mode
(Start-stop synchronous system 16 : 1) “H”
Initializes SCI interface
SCI input for setting micro program, factor and control register
SCI output for setting micro program, factor and control register
Input-output clock for CDI and CDO
Determines parameter transfer timing from transfer buffer to factor RAM when external trigger
is selected
Enters output timing into SO0 and SO1 when EXT clock is selected
Enters input timing into SI0 and SI1 when EXT clock is selected
Enters input-output clock for SI0, SO0 and SO1 when EXT clock is selected
Master clock input
Ground
16 bits serial input
16 bits serial output
Over flow detect
Used for testing Usually connected to +5V
Outputs bit 2 of factor RAM while delaying it by 1 bit. Used as a timing signal
Monitors sign bit of accumulator by setting test Reg
(When factor RAM is used as a timing signal, effective bit number of factor decreases)
Outputs bit 1 of factor RAM while delaying it by 1 bit. Used as a timing signal
Switches to test output of multiplier by setting test Reg
Outputs bit 2 of factor RAM while delaying it by 1 bit. Can be used as a timing signal
Turns OFF CE of SCI input
