Description
Default
(Binary)
PWR_MODE
Bits[7:6]:
01
00 = Normal operation (active)
01 = Default settings (startup)
10 = Low power (low power)
11 = Reserved
Trigger_Mask_2
Bit[5]:
0
If this bit is set, trigger 2 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 2, the data goes
directly to the destination register.
Trigger_Mask_1
Bit[4]:
0
PM_TRIG
(Note 1)
001C
Trigger_Mask_0
If this bit is set, trigger 1 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 1, the data goes
directly to the destination register.
Bit[3]:
0
If this bit is set, trigger 0 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 0, the data goes
directly to the destination register.
Trigger_2
Bit[2]:
0
If this bit is set, data is loaded into the trigger 2 registers.
Trigger_1
Bit[1]:
0
If this bit is set, data is loaded into the trigger 1 registers
(unsupported).
Trigger_0
Bit[0]:
0
If this bit is set, data is loaded into the trigger 0 registers
(unsupported).
PRODUCT_ID
001D PRODUCT_ID
Bits[7:0]:
01011101
This is a read–only register. However, during the programming of the
Unique Slave Identifier (USID), a write command sequence is
performed on this register but the value is not changed.
MANUFACTURER_ID 001E MANUFACTURER_ID
Bits[7:0]:
10100101
Read–only register

MANUFACTURER_ID
Bits[5:4]:

MAN_USID
001F
Read–only register
USID
Bits[3:0]:

Programmable USID. A write to these bits programs the USID.
Note 1: Unlike the complete independence between triggers 0, 1, and 2, and also between the associated trigger masks 0, 1, and 2, respectively (as described in the MIPI RFFE Specification),
when pin 7 is grounded, this device uses additional interactions between the provided trigger functions.
The delayed application of updated data to all triggerable registers in this device may be accomplished using any of the three triggers (0, 1, or 2), provided that the particular trigger
used is not currently masked off. If multiple triggers are enabled, any or all of those are sufficient to cause the data to be transferred from shadow registers to destination registers for
all triggerable registers in the device.
It is also necessary to disable all three triggers (i.e., set all three trigger masks) to ensure that data written to any triggerable register will immediately be written to the destination
register at the conclusion of the RFFE command sequence where the data is written.
