Note 1

Note 3
An access to data indicated by "-" does not have any effect on the LSI operation, and always reads 0.
The SRST[7:0] register at address 0111 is write-only.
The MSK receive data register at address 0110 and the REVNUM[3:0] register at address 1000 are read-only.
Test registers are located at addresses 1001 and 1010 and cannot be accessed. If an access is made to these
addresses inadvertently, the LSI operation is not guaranteed.
