Do we need to use the dedicated I2C for enabling this smartreflex SP-I2C or the general I2C GP-I2C for this? [In my system hardware i have connected I2C2 as GP-I2C & I2C4 as SP-I2C].
Answer1:I2C4 is used for smart reflex control.
How to enable the SMARTREFLEX_ENABLE bit in the DC/DC_GLOBAL_CFG register. As mentioend above, I2C4 is used for smart reflex control, can we use the same I2C4 itself to access this register & enable this bit. In clear phrase, does the TPS & OMAP supports this I2C4 communication only if we configure both the system in smart reflex control or we can do normal I2C communication through this & enable this bit.?
can we use the smart reflex & voltage control mode( for controlling other supplies) together?
SR is used only for the two core supplies, VDD1 and VDD2. I didnt understand the question, if this is not clear then please rephrase your question.
In my system I am using the LDO's - VIO.OUT, VAUX4.OUT, VMMC1.OUT, VPLL1,2,VDAC.OUT, VSIM also. My system comprises of OFF, SLEEP, ACTIVE modes( in ACTIVE Mode i have 6 different supply requirements). During SLEEP mode I need to keep the VDD1 and rest of the LDO supplies in SLEEP state & VDD2 alone in ACTIVE state.
So is there any possibility to control the supplies VIO.OUT, VAUX4.OUT, VMMC1.OUT, VPLL1,2,VDAC.OUT, VSIM using voltage control mode & VDD1 using smart reflex?
