Profile Registers
There are eight consecutive serial I/O addresses (Address 0x0E
to Address 0x015) dedicated to device profiles. All eight profile
registers are either single tone profiles or RAM profiles. RAM
profiles are in effect when CFR1[31] = 1. Single tone profiles are
in effect when CFR1[31] = 0, CFR2[19] = 0, and CFR2[4] = 0.
In normal operation, the active profile register is selected using
the external PROFILE[2:0] pins. However, in the specific case
when CFR1[31] = 1 and CFR1[20:17] ≠ 0000b, the active profile
is selected automatically (see the RAM Ramp-Up Internal
Profile Control Mode section).
Profile 0 to Profile 7, Single Tone Registers—Address 0x0E to Address 0x15
Eight bytes are assigned to each register.

No-dwell high
Effective only when the RAM mode is in ramp-up.
0 = when the RAM state machine reaches the end address, it halts.
1 = when the RAM state machines reaches the end address, it jumps to the start address
and halts.

Open
3
Zero-crossing
Effective only when in RAM mode, direct switch.
0 = zero-crossing function disabled.
1 = zero-crossing function enabled.

RAM mode control
See Table 13 for details.
RAM Register—Address 0x16
Four bytes are assigned to the RAM register.

Description
31:0
RAM word
The start and end addresses in the RAM Profile 0 to RAM Profile 7 control registers define
the number of 32-bit words (1 minimum, 1024 maximum) to be written to the RAM register.
