Figure 21-5 shows the basic timing of the LED matrix. The timing diagram assumes that
all 8 LEDs in column 0 (line LED 0) are activated. The repetition rate is ca. 157 Hz. The
line drivers are turned on and off with a delay to reduce the power consumption while
switching.
Actually, the selection of the active LEDs has to be done via the LED registers
LED_REG1 and LED_REG2. The timing for the subsequent two colums is equivalent to
the timing of column 0.
The number of LED rows (LED3...10) depends on the setting of the alternate function
register of Port2. Each line driver is able to sink 11 mA (sink current).
