MPC8349E-mITXE Board
The DS1339 RTC is connected to I
or write to the RTC through the I2C2 interface.
1.2.8
A compact Flash interface connects directly to the local bus without a PCMCIA controller. The true IDE
mode is the only compact Flash operating mode supported by this connection. Hot insertion and removal
is not supported. The MPC8349E universal programmable machine A (UPMA) is used to generate the
required timing for IORD and IOWR through the LGPL0 and LGPL1 signals.
The true IDE mode requires three address signals (A[0:2]) and two chip-enable signals (CE[1:2]) to
address the 10 registers in the AT task file. Therefore, glue logic is used to split CS3 into two regions. One
chip-select signal (CS3) is assigned to the compact Flash interface. Glue logic is used to generate the CE1
and CE2 signals required by the compact Flash. The logic simply uses the local bus address A22 to
determine which chip-enable signal is generated. See
