    CBM-909PC Series User’sManual 3. Description of signals 3.1 Description of control signals RESET The LSI is initialized by setting the reset pin at the low level. The reset pulse is required to be 10 S or more, while the LSI is operating. When the power is switched on, if using the ceramic oscillator, send the low level signal for 4 ms through the reset pin.

  • Page 14 CBM-909PC Series User’sManual This terminal will be in the “LOW” level under the low-speed operation mode (60 ms) and normal operation mode. It will be in the “HIGH” level during power down. By controlling (Refer to the circuitry diagram on p. XX, item XX) the DC-DC converter with the PWC signal, an operation voltage range between 3.5-6.0 V can be obtained.

    CBM-909PC Series User’sManual 3.2 Description of communication signals DB0~DB7 These are parallel 8 bit data receive pins. For more details on the timing of the parallel data reception, refer to the time chart 3.2-6. When the SLIN is setting the low level and the RDY outputs low level, the 8 bit data is latched by the STB signal (low level).

  • Page 23: Control Commands

    CBM-909PC Series User’sManual 4 CONTROL COMMANDS 4.1 Print commands: CR (0DH), LF (0AH) When the parallel interface is used, either CR or LF code can be selected by preset (S3). If the set CR or LF code is input, the data in the print buffer is printed and line feed is performed. When the serial interface is used, only the CR code becomes effective regardless of preset (S3).
  • Page 24 CBM-909PC Series User’sManual b-2) Input to RESET If the Low level is applied to the RESET pin for 4 ms or more, the power-down mode is reset. However, unless oscillation is stabilized, it is necessary to set the RESET pin to the Low level. After oscillation is stabilized, set the RESET pin to the High level.
  • Page 25 CBM-909PC Series User’sManual External character registration; ESC + & + A1 + A2 Up to 8-character pattern can be registered by inputting the pattern data following the ESC + & + A1 + A2 command. Registerable character addresses are the code table 20H through OFFH, that is 8 characters. The character address at the start of registration is “A1”, and that at the end of registration is “A2”.
