As for the enabled setting register of the DMA Transfer Update Enable Register (SGDER),
access is enabled to both the DMA Transfer Intermediate Register (SGDMAR) and individual
registers (SGAR, SGFR, SGNR, SGTCR, SGIDR, SGPCR).
−
During operation, in the case of changing a register value, meet the following either conditions.
(1)Sound generator is in the stop state (SGCR.BUSY="0").
(2)The changing comes between an interrupt occurrence and falling edge of the first tone pulse.
(The limit time = (Frequency Data Register [SGFR] + 1) x 1 PWM cycle)
When it meets neither condition, the sound output cannot guarantee the expected duty ratio.
