BUTTON_MODE Bit 7 set to 0 for 56-pin packages of CY7C68300C

Question: Why should the BUTTON_MODE Bit 7 be set to 0 for the 56-pin packages of CY7C68300C?

 

Answer:

The ATAPUEN  which is enabled or disabled by the BUTTON_MODE Bit 7 is available only in 100 pin package of CY7C68300C.  As the 56 pin package does not support this feature, BUTTON_MODE Bit 7 has to be disabled for this package.
