28-Pin Demo Board I
B.7.3
The ADC Display begins by displaying hex values 0x0A, 0x0D and 0x0C in sequence
to signify “ADC” test.
After the opening display sequence, the LEDs displays the Most Significant 4 bits of the
ADC result measuring channel AN0 (potentiometer RP1). As RP1 is manually turned
from one extreme to the other, the LED display should range from binary 0000 to 1111.
The firmware must be forced from this mode by command or Reset.
B.7.4
The RTC Display displays the Least Significant 4 bits of EXEC_REG_02 (RTC SEC-
ONDS). The LEDs should be seen to increment once per second in a binary progres-
sion (0x0-0xF) three times, then (0x0-0xB) once as the RTC SECONDS value
increments from 0x00 to 0x3B (59 decimal). The firmware must be forced from this
mode by command or Reset.
B.7.5
This feature displays the state of the 4 signal pins on the communications connector.
LED1: PIN 1 (AUX1)
LED2: PIN 4 (SDA)
LED3: PIN 5 (SCL)
LED4: PIN 6 (AUX2)
Normally, LED2 and LED3 should be illuminated if the I
the SCK is not held low. The firmware must be forced from this mode by command or
Reset.
B.7.6
The RESET Display is executed on Reset/power-up or by command. The sequence is
a series of individual displays as follows:
1. PING-PONG display: cycles: 2 (i.e., LED1,2,3,4,3,2,1,2,3,4,3,2,1)
2. Blink all LEDs in unison: cycles: 1 (i.e., 1 sec OFF, 1 sec ON, 1 sec OFF)
3. ADC display (described above): cycles: perpetual
B.7.7
Blink all LEDs in unison at 1-second intervals (i.e., 1 sec OFF, 1 sec ON, 1 sec
OFF),...This feature uses time based on the Timer1 low-power oscillator and external
32 kHz tuning fork crystal.
