SH67P54/K54/P53/K53 EVB Diagnostic LED: Power LED: The LED will be turned on when the EVB is powered. HALT LED: The LED will be turned on when the system is in HALT mode. STOP LED: The LED will be turned on when the system is in STOP mode. Oscillator setting: The SH67P54/K54/P53/K53 EVB supports 2 on board oscillators, one is low frequency oscillator (OSC: 32KHz Crystal or 262KHz RC) and the other is high frequency oscillator (OSCX: 400K –4MHz Ceramic or Internal 4MHz ).

SH67P54/K54/P53/K53 EVB Notes for TIMER 2.9.1 When setting the Timer Counter, write first T0L, then T0H. 2.9.2 After setting TM0, T0L, T0H, there is no need to rewrite after the Timer counts overflow, otherwise it will cause a time error every time. The timer is interrupted by that the reload registrar that was set in different time.

SH67P54/K54/P53/K53 EVB 2.13 Notes for key scan 2.13.1 If there is no surplus of SEGMENT, it is necessary to use audion to separate the LCD displaying and key scan. If there are more SEGMENTs, which can be directly used as scanning output line, then each SEGMENT must have pull-up resistors.
