WXAD : Write X Address for Y and C
WXAD is a write X address (or line address) input for Y and C. WXAD specifies line address. 9 bits
of write X address data are input serially from WXAD.
WYAD : Write Y Address for Y and C
WYAD is a read Y address (or bit address in a certain line) input for Y and C. WYAD specifies the
first bit address of consecutive serial write data in the line whose line address is defined by X write
address from WXAD. 10 bits of write Y address data are input serially from WYAD.
IE : Input Enable for Y and C
IE is an input enable which controls the write operation. When IE is high, the input operation is
enabled. When IE is low, the write operation is masked. When WE/WY signal is high, and IE low,
the internal serial write address pointer is incremented on the rising edge of WCLK without actual
write operations. This function facilitates picture in picture function in a TV system.
