High Speed Data UART
The RZ/G1E HDMI Add-On Module supports one full functional high speed UART interface through RZ/G1E
CPU’s
HSCIF2 interface. This HSCIF2 signals from the CPU is connected to MAX3232E RS232 transceiver which converts
3.3V level into RS232 level. The RS232 level converted signals are available in 6pin header (J3). The HSCIF2 UART
interface 3.3V CMOS level signals also optionally connected to the J3 header. This high Speed UART header is
physically located at the top of the board as shown below.
