ACRM | Active CRAM Monitor (Read Only) | ||||||||
This bit indicates which CRAM is being accessed by the DSP when adaptive mode is disabled. When adaptive mode is enabled, this bit has no meaning. | |||||||||
0: CRAM A is being used by the DSP | |||||||||
1: CRAM B is being used by the DSP | |||||||||
AMDC | Adaptive Mode Control | ||||||||
This bit controls the DSP adaptive mode. When in adaptive mode, only CRAM A is accessible via serial interface when the DSP is disabled (DAC in standby state), while when the DSP is enabled (DAC is run state) the CRAM A can only be accessed by the DSP and the CRAM B can only be accessed by the serial interface, or vice versa depending on the value of CRAMSTAT. When not in adaptive mode, both CRAM A and B can be accessed by the serial interface when the DSP is disabled, but when the DSP is enabled, no CRAM can be accessed by serial interface. The DSP can access either CRAM, which can be monitored at SWPMON. | |||||||||
Default value: 0 | |||||||||
0: Adaptive mode disabled | |||||||||
1: Adaptive mode enabled | |||||||||
ACRS | Active CRAM Selection (Read Only) | ||||||||
This bit indicates which CRAM currently serves as the active one. The other CRAM serves as an update buffer, and can accessed by serial interface (SPI/I2C) | |||||||||
0: CRAM A is active and being used by the DSP | |||||||||
1: CRAM B is active and being used by the DSP | |||||||||
ACSW | Switch Active CRAM | ||||||||
This bit is used to request switching roles of the two buffers, i.e. switching the active buffer role between CRAM A and CRAM B. This bit is cleared automatically when the switching process completed. | |||||||||
Default value: 0 | |||||||||
0: No switching requested or switching completed | |||||||||
1: Switching is being requested |
