RESET CIRCUIT

With RES pin (No 94 pin) set to "Low" level, STB 1

㨪

3 (No's 9 

㨪

11 pins) are made in high impedance state cutting 

off current supply to Thermal Head. Perform pull-up or pull-down according to Thermal Head.  Further, with a 

watchdog timer output (CPU, etc.) connected to RESO pin (No 95 pin), checking is performed on every ROM access 

time, thus protecting Thermal Head.

For other output pins, those with pull-up are made "High", while those without are made high impedance.    Refer to 

the above mentioned "Terminals and Their Functions."

                                 

Recommended Reset IC:    SEIKO Electronic Co., Ltd.    S-804HNM

The gate array, when Reset pin (Pin 94) is held at "low" level for 1 

P

s or more and returned to "high" level under 

supply voltage of 5V 

r

5%, is reset released and initialized.
