2.
PWC
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.
3.
SLIN
Setting the SLIN pin to the Low level places this system in the on-line mode and causes it to be ready to receive
the data.
When this SLIN is at the High level, the system is placed in the off-line mode and can not receive the data. At this
time, it receives the signal PF (paper feed).
This system samples the SLIN signal in the following cases.
•
After completing a system reset
•
After resetting the power-down mode
•
While the data is ready
•
While the paper is being fed
When the SLIN signal is set to Low during paper feed by the PF signal, the system is placed in the on-line
V
mode after ocmpleting that feed.
When the SLIN signal is set to High during the text mode, the system is placed in the off-line mode after
V
printing the data in the print buffer.
When the SLIN signal is set to High during the bit image mode, the data in the print buffer is cleared and the
V
bit image mode is also reset.
4.
PF
This is a manual paper feed pin and doubles as a self test printing pin.
This pin accepts a signal only when the system is in the off-line mode, except the power-down mode.
Line feed is performed while this pin is held at the Low level (30 ms or more). To conduct a self printing test, set
the PF pin to the Low level and turn on the power or input the RESET signal.
5.
INT
This is used to reset the power-down mode by the DC2 and DC3 command.
Resetting the power-down mode by the DC2 command.
V
This is done by setting the INT pin to the Low level for 10 s or more.
Resetting the power-down mode by the DC3 command.
V
This is done by holding the INT pin at the Low level until XTAL oscillation is stabilized, and then, by setting
the pin to the High level.
6.
ES
Setting this pin to the Low level interrupts system control and stops oscillation, resulting in the power-down
mode.
Resetting the power-down mode by the ES signal. This is done by holding the ES pin at the high level and
inputting the RESET signal.
