1.13.3 Rocker Switches
1.13.4 Accelerometer
Freescale Semiconductor
Eight rocker switches (SW5) are provided for user application development.
These switches are active low and input a logic low when set to the closed
position. There are no external pullups on these switches so the internal pullups
should be enabled on the MCU port pins to ensure proper operation. Port A pins
can be disconnected from the rocker switches by removing the appropriate
jumper. The rocker switches are connected as described below
A Freescale MMA6260Q accelerometer (U5) is provided to assist users in
developing accelerometer based application code. The MMA6260Q provides
output data in the X and Y direction and has a self test mode. The MMA6260Q
is a 3.3V part and is connected to the MC9S08AW60 through the use of a level
translator. The X and Y outputs are connected back to the MCU both directly
from the accelerometer (3.3V signals) and amplified to 5V through the use of
op-amps. The self test is an active high input to the accelerometer. When a logic
high is applied to the self test pin the center plate of the accelerometer is
deflected, the resultant deflection is measured by the accelerometer's ASIC, and
a proportional output voltage results. The MCU port pins can be disconnected
from the accelerometer by removing the appropriate jumper. The accelerometer
is connected as described below
