Register Map
Table 15-1 on page 426 lists the SSI registers. The offset listed is a hexadecimal increment to the
register’s address, relative to that SSI module’s base address:
■
Note:
SSI0: 0x4000.8000
Ensure that the SSE bit in the SSICR1 register is disabled.
Write the SSICR1 register with a value of 0x0000.0000.
Write the SSICPSR register with a value of 0x0000.0002.
Write the SSICR0 register with a value of 0x0000.09C7.
The SSI is then enabled by setting the SSE bit in the SSICR1 register to 1.
The SSI must be disabled (see the SSE bit in the SSICR1 register) before any of the control
registers are reprogrammed.
