FUNCTIONS
B.7.1
The PING-PONG display is useful in testing the four LEDs which are illuminated
individually and in sequence as seen below. The following pattern is executed at a
100-millisecond step interval.

B.7.2
Timer1 Test provides a basic test of the auxiliary clock used for the RTC. The 28-Pin
Demo Board employs a 32 kHz crystal on TIMER1 LP Oscillator to provide a 1-second
interval for the RTC emulated device. The test begins by clearing the one-second flag,
then waits a maximum of 1.1 seconds to see if the flag is reset. Alternatively, the HOST
can test the RTC clock by examining EXEC REGISTER 0x02 at logically timed
intervals.
