■ Slot status register

MSLC (W); MonitorSLot Call

Specify the slot number you want to monitor in the "CA" register.
"0H" becomes "SLOT0", and "1FH" becomes "SLOT31".

Since it is a write-only register, the written value cannot be read.
Even if you read it, the value is indefinite and has no meaning, so please be careful.

CA (R); Call Address

The slot with the number set in this register can read the address of the waveform data currently being read as the number of relative samples (number of samples = number of samples of waveform data) from "SA" (start address).
Since the LSB (least significant bit) of the value that can be read here indicates a 4K (4096) sample, when the read value is "1H", the monitored slot should have a waveform address of at least 4K sample from "SA". You are reading.

Since it is a read-only register, be sure to write [0b] when writing a value.
