3.3 

Mask ROM ordering 

Sound quality and operation must always be checked using flash memory on the Cinderella board before ordering 
a mask ROM. Please confirm that there are no problems before ordering a mask ROM. 

When ordering a mask ROM after evaluation with flash memory, please check that the voice data content 
matches the initialization information (clock division ratio, sampling frequency, and DAC bit width). For 
example, note that if the internal ROM is created in 8-bit with 8F-bit evaluation using flash memory on the 
Cinderella board (16.384 MHz clock), the clock division ratio and DAC bit width must be altered as shown in 
Table 3.2 (for a sampling frequency of 8 kHz). The voice data must also replace 8F-bit with 8-bit at this time.
