MOTOROLA
NOTE:
The SCK pin is the serial clock pin for synchronizing transmissions
between master and slave devices. In master mode, SCK is an output.
In slave mode, SCK is an input.
In a multiple-master system, all SCK pins are tied together.
In master mode, the SS pin can be:
In slave mode, the SS pin is always a slave-select input.
Table 17-2
Reading reserved addresses (0x00cb_004 and 0x00cb_0009 through
0x00cb_000b) and unimplemented addresses (0x00cb_000c through
0x00cb_000f) returns 0s. Writing to unimplemented addresses has no
effect. Accessing unimplemented addresses does not generate an error
response.
1. S/U = CPU supervisor or user mode access. User mode accesses to supervisor only
