3.10 User fonts RAM
The user fonts RAM have 288 locations, which are allocated between (row 0, column 0) to (row 7, column 35)
to specify 8 user programmable fonts, as shown in Figure 6. Each user programmable font consists of 12x18
dot matrix which data are stored in 36 bytes registers. And each line of dot matrix consists of 2 bytes data,
which include 4 dummy bits as shown in figure 7 and figure 8. For example, font 0 is stored in row 0 from
column 0 to column 35 and font 1 is stored in row 1 from column 0 to column 35, etc.
