2208	Roger, All the I/O pins of the 9S12DP256 and all other HCS12 devices have a nominal input threshold of VDDX/2. For VDDX of 5V the threshold is 2.5V. The...	Doron Fael doronf@...	Feb 2, 2003 8:46 pm

2211	SPI, by its very nature and definition is a full-duplex, bi-directional protocol. It does not offer a "one-line, half duplex" mode of operation. You should...	Robert Smith bobsmith523236	Feb 3, 2003 4:55 pm
2212	Hi Roger, You must program an aligned word to the EEPROM of the DP256. Attempting to program a misaligned word or a byte will cause an ACCERR error. This is...	djsimpson100 <david@.... djsimpson100	Feb 3, 2003 11:24 pm
2213	Thanks for your kindness. I omitted Clock line because Clock line is basis of SPI communication. I mean the one line communication is TX & RX Line. I want send...	j2bichon	Feb 4, 2003 12:27 am

2220	Hi, have a look at the SPI control register 1 and 2. There are some bits to arrange what you want to do. These may vary in name depending on the chip you use,...	Peter Lissenburg peterlissenburg	Feb 4, 2003 1:26 am
