19.3.2.10 SSG Interrupt Flag Registers (SSGIF)
The SSGIF is the Interrupt flag.
19.3.2.11 Buffer Register of SSGAMP (SSGAMPB)
The SSGAMPB is the buffer register of SSGAMP. It determines amplitude directly.

RNDI
SSG Ready for Next Sound Data Interrupt —
The interrupt flag will be set in two cases: one is when the current sound configuration data is loaded into internal
buffer registers, after the flag is set, user can configure the registers for the next sound data. RNDI will get set
as well when the reload time is reached and RDR is cleared. Writing 1 to this bit will clear the flag bit, writing 0
has no effect on this bit. The details of internal registers loading refer to
Section 19.4.5, “Register Reload
0 The SSG is not ready to config the next sound data.
1 The SSG is ready to config the next sound data.
