i am using the LPC1347.

There is a register named PRESETCTRL.

With this register i can reset the Hardware from SSP0, I2C and SSP1.

To Reset the Hardware i must clear then coresponding bit to "0"

To activate the peripheral i must set the bit to "1"


Question: Is there a minimum time limit, between reset and set to this bit,

so the Hardware can do the internal reset operation ?


Reset the Bit


Set the Bit

wait until ready ???



after doing the reset, do i need to wait until Hardware is ready ???


very thanks for information
