RS232 FLASH load can be done with standard PC with a serial port and
FLASH loading software. Upload is also possible with this software. On
the PDA module RS232 FLASH download software is part of the BIOS.
RS232 FLASH download commands are integrated to maintenance
software.
FLASH programming voltage is generated on PDAPWRU. FLASH
memory content validity can be checked by calculating error check code
and comparing it to precalculated one.
– PROCU – PDAPWRU
PDAPWRU generates 3.3V VSYS for overall system usage and 5V for
FLASH programming. FLASH programming voltage can be switched off
with 5VPDX signal when it is not needed. Switchmode powersupplies are
used for VSYS and LCD Vee. LCD display contrast control (bias) is
generated by PWM unit in E3G CPU. This signal controls LCD Vee power
supply on PDAPWRU. LCD bias and LCD logic voltages can be switched
on and off by PROCU with LCDVEE and LCDVCC signals. PDAPWRU
generates power good (PWRGOOD) signal for PROCU reset purpose.
VBACK is always available for real time clock.
– PROCU – LCDM
640 x 200 LCD screen (8 actual grey scales) on LCDM is controlled by
PROCU. Soft keys and scroll keys on LCDM module are connected to the
keyboard controller on PROCU.
– PROCU – SIRU
IrDA transceiver and RS232 buffer are located to SIRU. Same RXD and
TXD lines are used for both devices. When the device is not used the
transmit line must be in high impedance state. Only one device is allowed
to be enabled at a time. RS buffer have two control signals. RSENX to
enable transmit line and RSSHDX to enable charge pump. IrDA tranceiver
is enabled with IRSHD signal. External RS232 signals meet EIA/TIA–232
specification.
– PROCU – EMIU
EMI Unit is passive unit to reduce EMI noise on the lines that are located
out of the shielding.
I/O usage on E3G CPU
The E3G CPU have configurable I/O pins that are used like described on
Table 21.
