2.1.3 Initialization
This printer is initialized when the power is turned on or when the I-PRIME-N signal is input
from the host side via the parallel interface.
For the initializing operation, the RST-N signal is first output from the reset circuit to reset the
MPUs and LSIs. When resetting ends, the program starts and the LSIs are reset by MPU via
LSIRST-N. Reset operation by I-PRIME starts program to initialize, but does not reset the MPU.
The program here sets the mode of the LSI including the MPU, checks the memories (ROMs
and RAMs) and, after USB I/F control LSI initialization and USB I/F bus opening, performs
carriage homing operation and LF motor phase setting.
Finally, the program establishes the interface signals (P-I/F: ACK-P signal sending, and S-I/F:
BUSY-N signal off) and lights the SELECT lamp to inform the ready state for receiving to the
host side and ends the initialize operation.
