Figure 7-14: Accelerometer Signal Output ACC_EN (J16)
Enables the 3-axis accelerometer. This is the default setting.
Puts the 3-axis accelerometer into sleep mode. The user may control
PTC4 in firmware to enable or disable the accelerometer. In this
configuration, the user needs to pay close attention to LED PTC4 and
RSTO configuration.
The accelerometer output signals are jumper settable to PTA7, PTA6,
PTC7, and PTA1. PTA6 and PTC7 share the same Y-axis signal. By
default, the Y-axis signal is connected to PTA6.
