Delta Sheet for the Version 3.4
This document describes the latest MUNICH32 (Version 3.4) in relation to the
Version 3.2 and hence is a “Delta Sheet“ which references the MUNICH32 User’s
Manual 01.96 (V 3.2).

1.3 Functional Upgrades
1.3.1 Capability of minimum one byte reception in HDLC CS=1 mode
The MUNICH32 V3.4 is able to receive frames with 1 Byte length. This capability is
available in HDLC CS=1 m ode only. In order to use this new functionality bit #9 of the
channel specification, which is called NSF (=no short frame indication), has to be set to
a logical ’1’.
When this bit is set to ’1’ with CS=0 aborted frames (> 2 byte ) are written into the shared
memory, last 2 bytes are invalid, ERR / CRC interrupt is generated, status RA bit is set.
In all other modes ( HDLC protocol ) this bit has to be set to logical ’0’!
The new mode has all features of the HDLC mode with the following changes:
• In case of 1 Byte (or greater) frame received, the data is copied to the RAM
• The short frame interrupt is not generated!
• The short frame status bit is not set the same way as described in HDLC case
• The FI interrupt is generated the same way as described in HDLC case
Note: CRC is still calculated and checked and e.g. a frame of 1 or 2 Byte length (in
CRC16 Mode) will always cause an FI+ERR interrupt.

1.3.2 Reset
The RESET behaviour was changed between MUNICH32 V3.3 and MUNICH32 V3.4:
After po wer up a l o gi c al ’1’ at th e re se t pi n of th e M UNICH32 V 3. 4 s ets t he de v ic e int o a
reset state where the complete microprocessor bus interface is tristated and the internal
reset sequence is started.
The trailing edge of the reset starts the last part of the internal reset sequence and takes
about 12 SCLK cl ock cycles. It is no t allowed to give an AR du ring these first 12 SC LK
cycles after the trailing edge of RESET.
1.3.3 New version number
The version number is identified in the interrupt information bits VN(3:1):
these bits are ’110’ for version 3.4.
The version number in the boundary scan ID code is set to ’0110’ for version 3.4.
1.4 Electrical Characteristics
The MUNICH32 V3.4 is available for the extended range of temperature:
All other electrical characteristics are as specified in MUNICH32 User’s Manual 01.96.
Examples:
a) 0x7E, data1, 0x7E... • data1 in RAM
• status SF-Bit set
• FI indi cat ion inte rru pt
generated
• No SF interrupt
• ERR interrupt due to wrong
CRC
b) 0x7E, data=0xFC(or 0xFD, or 0x7F), 0x7E • no data in RAM
• SF, ERR-interrupt
