Table 42
APU coefficients: 4 bytes (read/write, unrestricted special block type
Table 43
Explanation of bits in Table 42
Note
1.
Default settings (settings value after a hard reset).
The APU coefficient block type is a special one:
Block accesses may start at any individual coefficient (each has its own local address)
Block accesses may also extent past RR (the block access will wrap around to LL).
7.6.6.7
Interrupt control
Interrupt generation is controlled using two separate single byte local registers.
Table 44
Interrupt event register: 1 byte (read-only, unrestricted type, local address = 1CH)
The separate bits of the interrupt event register indicate the occurrence of the events shown in Table 44
