Special Note
1. UC-7420/7410’s kernel will store the “pressed key history” in a buffer. The maximum buffer
size is 31 keys. If the buffer overflows, the first key of the 31 that was pressed will be dropped,
without sounding the buzzer.
2. Currently, UC-7420/7410 does NOT support pressing more than 1 key at the same time.
