 		 #128078 - REN_0
Responding to: ???'s previous message
SCON0 = 0x13; //Mode 0, baud 24/12, enable receive,TI=1;RI=1;

Disable REN_0 and clear TI for transmission.
Then put data to SBUF0
TI is asserted when the transmission finishes.

Enable REN_0 and clear RI for reception.
Then TXD0 starts to clock the SCK of the SPI
RI is asserted when the reception finishes.

When the UART mode 0 is used as an alternative of SPI,
- clock polarity and phase is limited
- The bit order is reversed

   How to post legible code            01/01/70 00:00      
      I dunno            01/01/70 00:00      
      thanks            01/01/70 00:00      
         who is is this microresistor expert?            01/01/70 00:00      
         You, too, can be expert!            01/01/70 00:00      
            well, I did            01/01/70 00:00      
               But of course, you prefer to be obtuse            01/01/70 00:00      
                  no, I am not 'obtuse', just trying to get to the s            01/01/70 00:00      
   Legible code posted,please continue the discussion            01/01/70 00:00      
      That's better            01/01/70 00:00

         I'm puzzled            01/01/70 00:00      
            Bible Time!            01/01/70 00:00      
               Separate RXD0OUT pin            01/01/70 00:00      
                  Now I'm confused, too!            01/01/70 00:00      
                  data is not transmitting            01/01/70 00:00      
               OUCH!            01/01/70 00:00      
                  1Mhz clock            01/01/70 00:00      
                     reply            01/01/70 00:00      
   why no body is replying            01/01/70 00:00      
      Richard, where are you, he is using mode 0!            01/01/70 00:00      
         I didn't have anything to contribute ...            01/01/70 00:00      
      Because no particular error            01/01/70 00:00

            Debug monitor?            01/01/70 00:00      
               connected to SI0-0            01/01/70 00:00      
                  Debug monitor!!            01/01/70 00:00

                        monitor switches the UART mode            01/01/70 00:00      
                           Tested with SIO-1            01/01/70 00:00      
                              Monitor comes from EEPROM?            01/01/70 00:00      
                                 problem solved            01/01/70 00:00      
                                    Not yet            01/01/70 00:00      
                                       12Mhz            01/01/70 00:00      
                                          Then what was the cause, after all?            01/01/70 00:00      
                                             Don't leave it unsolved            01/01/70 00:00      
                                                ALLOCATE_EXTERN??            01/01/70 00:00      
                                                   ALLOCATE_EXTERN fixes FX2 xdata registers addr            01/01/70 00:00      
                                                      EXTERN ALLOCATE            01/01/70 00:00      
                                                         ALLOCATE_EXTERN fixes PORTECFG address            01/01/70 00:00      
                                                            EXTERN_ALLOCATE            01/01/70 00:00      
                                                               Its ALLOCATE_EXTERN .not EXTERN_ALLOCATE            01/01/70 00:00
