DESCRIPTION OF BLOCK FUNCTIONS
Generates a clock required for the DSP to control a system clock stop in the waste state and an entire clock
stop for sleeping.
Controls an INT interrupt, an overflow interrupt, and a DMA interrupt.
Generates a program address and decodes an instruction to control the entire DSP .
Generates an address required for memory access. It supports a circular addressing function to control the
DMA access pointer and the stack pointer.
Performs data operations such as product addition, arithmetic operations (multiplication, division, addition and
subtraction), logic operations, and shift operations.
Controls access to the memory space including instruction reading, data memory access and mapped I/O
access.
This is a data memory for data operations. A and B use different banks, enabling double transfer without a
wait. (ARAM = 4 kwords, BRAM = 4 kwords)
Sets table data required for applications.
Sets program data.
Supports a macro valid for applications
Serial I/O: Two serial ports for transmitting CODEC data.
One serial input 1 system for setting operating mode (SMODE)
