Output Mechanisms
6.1
Introduction
The MPR083 has three primary methods for reporting data in addition to an IRQ output that is described in Chapter 7. The three
output systems are described in this section.
6.2
Instantaneous
The Instantaneous output shows the current status of the user interface. This information is displayed in terms of the current
rotary position that is touched. Only one touch can be shown at a time.
6.2.1
Rotary Status Register
The Rotary Status Register is a read only register for determining the current status of the rotary. The I2C slave address of the
Rotary Status Register is 0x02.
Figure 20. Rotary Status Register
6.3
Buffered
The Buffered output is done through a FIFO. The FIFO will buffer every touch that occurs up to 30 values before the buffer
overflows and data is lost. Any time data is read from the FIFO it is pulled from the buffer and the next item becomes available.
The buffer can be cleared (NDF goes high) by either reading the last entry or attempting to write to the register.
The buffer settings are configured in the Rotary Configuration Register as described in Section 3.4.
6.3.1
FIFO Register
The FIFO Register is a read only register for determining the current status of the rotary. Any time a write is issued to this register
the buffer will be cleared. The I2C slave address of the FIFO Register is 0x00.
