Bit Description (cont.)

7:4 DID: Display ID nibble. This 4-bit nibble reflects the latched state of the four LCD data lines. The state of the four LCD

data lines is latched by the LCDEN bit and always reflect the last state of these lines before the LCD controller was

enabled. These bits identify the LCD display panel.

cleared by a system reset or by writing to the HALT or STDBY locations.

2 WUDR: Wake-up direct read. This bit reflects the non-latched state of the WAKEUP signal.

1 DCDET: This bit is set if the main adapter is powering the system (the inverted state of the NDCDET input pin).
