2.15.6 Slice RAM
Store 18-line slice data. There are 3 types of Slice data : PDC, VPS and VBI. All data are stored to
addresses which corresponds to slicing line (ex. 22 line' data is stored to addresses 20016 to 21716 ).
24 addresses (SR00x to SR17x) are prepared for 1 line, slice data is stored in order from LSB side.
Then, slice datas and field information are stored to the top address of each line.
Slice RAM composite is shown in Table 2.15.6.
Table 2.15.6 Slice RAM composition
For accessing to slice RAM data, set accessing address (SA9 to SA0) (shown in Table 2.15.6) to slice
RAM address control register (address 020E16 ). Then read out data from slice RAM data control
register (address 021016 ). When end the data reading, slice RAM address control register incre-
ments address automatically. Then, next address data reading is possible. Do not access to unused
area of each character codes. Must set address to each line because unused area has no address'
automatically increment.
Slice RAM bit composition is shown in Figure 2.15.19, Slice RAM access registers are shown in
Figure 2.15.20 and Slice RAM access block diagram is shown in Figure 2.15.21.
