Notes:
1. Refer to NXP’s UM10204 I2C-bus specification and user manual, Revision 03, for further details:
www.nxp.com/acrobat_download/usermanuals/UM10204_3.pdf.
2. Only I2C pullup voltages (VDDI2C) of 1.71 to 3.63 V are supported. Must write register 27[7] = 1 if the I2C bus voltage
is less than 2.5 V to maintain compatibility with the I2C bus standard.
