For applications that use a system host to program
the initial configuration after power up, this general procedure can be followed
from the register map data generated and exported from TICS Pro:
- Apply power to the device to start in I2C or
SPI mode.
- Write the register settings exported from TICS Pro while
applying the following register mask (do not modify mask bits = 1):
- Mask R23 = 0xFF (Device reset/control
register)
- Write 1 to R21[6] to assert
SYNC. Clocks which should not be synced should have the SYNC functionality
in their divider path disabled.
- Write 1 to R23[6] to assert device soft-reset. This does
not reset the register values.
- Write 0 to R23[6] to exit soft-reset and begin the PLL
start-up sequence.
- Write 0 to R21[6] to
de-assert SYNC and release all clocks to start-up synchronized.
