Note:
1. Transfer specifications
Type N : Normal transfer from the microcomputer to the DSP
Type E : Transfer using the set pulse (synchronous with VD) or the reset signal (used as a
synchronous pulse in the DSP) sent from the microcomputer to the RS latch in the
DSP
Note: This cannot be set during the standby mode.
Type R1 : Data transfer (1) from the DSP to microcomputer
Type R2 : Data transfer (2) from the DSP to microcomputer
