5. CHARACTER PATTERNS
The
μ
PD6461, 6462 can display 256 (
μ
PD6461)/128 (
μ
PD6462) character patterns, including alphanumerics, Kanji
characters, and symbols, which are stored in the character generator ROM. Each pattern in the character generator ROM
can be modified by specifying a mask code option. However, the display-off data at character address FEH (
μ
PD6461)/
7EH (
μ
PD6462) and end code for second-byte continuous input at FFH (
μ
PD6461)/7FH (
μ
PD6462) cannot be modified.
No character pattern can be stored at these addresses.
When none of the 12
×
18 dots are filled for a character pattern at addresses 00H to FDH (
μ
PD6461)/00H to 7DH
(
μ
PD6462), the character pattern is called blank data. Character address FEH (
μ
PD6461)/7EH (
μ
PD6462) contains display-
off data. Blank data and display-off data are represented in the same way (with no dots filled) in character patterns shown
on the following pages, but they are different as follows:
Table 5-1 The Differences between Blank Data and Display-off Data
You cannot specify display-off data for addresses other than FEH (
μ
PD6461)/7EH (
μ
PD6462) when using a mask code
option. Blank data, however, can be specified at any address from 00H to FDH (
μ
PD6461)/00H to 7DH (
μ
PD6462) (address
FFH (
μ
PD6461)/7FH (
μ
PD6462) cannot be used because it contains the end code for second-byte continuous input).
The character patterns of the
μ
PD6461GS-101/102,
μ
PD6462GS-001 (NEC’s standard model) are shown on the
following pages.
