TYPE
Base address for audio input Channel 2; this value specifies a
byte address. The lower two bits are forced to zero.
protection address for audio input Channel 2; this address
could be used to specify a upper limit for audio access in memory
space
reserve
base address of the page table, see Section 7.2.4
mapping enable; this bit enables the MMU
reserved
interrupt limit; defines the size of the memory range, that
generates an interrupt, if its boundaries are passed
