The ASCII representation of the UART-frames is identical to the hexadecimal representation of the 

TWI-frames. Even the device-ID must be transmitted when UART is used; see light green telegram 

byte for TWI transmissions below. So the given documentation refers to TWI but is valid for UART 

communication as well. 

 

Example: 

Documentation of the TWI telegram that reads the ZX Firmware Version 

 

The corresponding TWI telegram in 

hexadecimal 

representation: 

TWI write frame ->  

 

88 F0 0E EF                    

 

length: 4 Bytes 

TWI read frame ->  

 

00 03 00 05 8D 35             

 

length: 6 Bytes 

 

The corresponding UART telegram in 

ASCII 

representation: 

UART request telegram -> 

 88F00EEF<LF>   

 

 

length: 9 Bytes 

UART receive telegram->  

000300058D35<LF> 

 

 

length: 13 Bytes 

 

The length of the UART frame is always calculated as: (length of TWI frame) * 2 + termination 

character. 

 

CRC (CCIT format) is calculated from the command and data frame without the TWI-address. See 

details in next subchapter. 

3.4.2

 

TWI Interface 

 

The TWI communication interface is operated via SCL and SDA (Pin 4 and Pin 5) according to 

standardized physical TWI protocol definition up to 100 Kbit/s. No pull-up resistors are implemented 

for both wires; this must be done on the host side. A proper GND reference of the applied signals has 

to be ensured. Signal-GND (Pin 3) can be used for this. 

Please refer to the original Philips specification that can be found at this URL:

NOTE 

Please pay attention to the following deviations from the original 

Philips I²C specification: 

 

Max high level output voltage 3.3V  

 

1 mA current sink capacity 

 

Pull-Up resistors must be chosen in accordance with the current
