23.2.5
Address: 0F2C3H
Access: R/W
Access size: 8 bits
Initial value: 00H
MD0LEN is a special function register (SFR) to set the tone length code of a melody when melody mode is selected and
buzzer output duty when buzzer mode is selected.
[Description of Bits]
• M0LN5, M0LN4, M0LN3, M0LN2, M0LN1, M0LN0 (bits 5-0)
Initial value
MD0LEN
For tone length codes, see Section 23.3.3, "Tone Length Codes".
Note: In buzzer mode, the M0LN5 to M0LN4 bits are not used.(Don't care)
