LED Matrix
The one 7x5 LED matrix device on the eZ80
memory-mapped device that can be used to display information, such as
programmed alphanumeric characters. For example, the LED display
sample program that is shipped with this kit displays the alphanumeric
message:
To illuminate any LED in the matrix, its respective anode bit must be set
to 1 and its corresponding cathode bit must be set to 0.
Bits 0–6 in Table 7 are LED anode bits. They must be set High (1) and
their corresponding cathode bits, bits 0–4 in Table 9, must be set Low (0)
to illuminate each of the LED’s, respectively.
Bit 7 in Table 7 does not carry any significance within the LED matrix. It
is used for the general-purpose port as a control bit.
Table 9 indicates the multiple register functions of the LED cathode,
modem, and triggers. This table shows the bit configuration for each cath-
ode bit. Bits 5, 6, and 7 do not carry any significance within the LED
matrix. These three bits are control bits for the modem reset, Trig1, and
Trig2 functions, respectively.
