MD0CON is a special function register (SFR) to control a melody and the buzzer.
[Description of Bits]
• BZMD (bit 1)
• M0RUN (bit 0)
Note:
For melody output, use the 2×low-speed clock (LSCLK×2).
Enable the 2×low-speed clock by setting bit 2 (ENMLT) of frequency control register 1 (FCON1) to “1” and then start
melody output by setting M0RUN to “1”.
Initial value
MD0CON
The BZMD bit is used to select melody mode or buzzer mode.
The M0RUN bit is used to control start/stop of the MD0 output.
