4.15 BIT DATA PROCESSING METHOD

This gate array is equipped with a data processing circuit which faciliates processing of bit data when print data are 

developed in memory.

a.) 180° turning circuit (MSB/ LSB switching)

b.) Double character conversion circuit (8 bit 

→

  16 bits conversion)

c.) 90° turning circuit (8 bits x 8 bits turned by 90°.)

The 180° turning circuit and the double character conversion circuit perform data processing in 1 byte unit, while the 

90° turning circuit performs it in 8 bytes unit.    The methods are shown as follows:

a) 180° Turning Circuit

1. Write, into the XX05h processing bit data buffer, the bit data for which turning is to be performed.

2. With data being read out from output of 180° turned XX05h address, data which have been turned by 180° are 

obtained.    (Address being the same.)

2. With data being read out from the lateral double lower 8-bit output and the lateral double upper 8-bit output of 

Addresses XX06h and XX07h, data having been processed in 16 bits are obtained.
