TOUCH SCREEN CONTROLLER
The formula for determining P.P.S. is:
On application of power, an internal reset is generated that clears all bits in registers 0, 1, and 6. Register 7 is set to
32 giving a rate of 86 PPS. Note that clearing register 6 puts the IC into the power down condition.
The interrupt on the MK712 can only be cleared by reading a register or by writing register 6 to the power down
condition. After a fault condition, initialize the MK712 by writing register 6 to zero and then writing register 6 to the
desired value. This will always clear pending interrupts.
