Have you actually read this datasheet yourself? If you have, you should at least be able to put forward some suggestions of your own... HCTL 2032 Datasheet said:
Bus Interface The bus interface section consists of a 32 to 8 line multiplexer and an 8- bit, threestate output buffer. The multiplexer allows independent access to the low and high bytes of the position data latch. The SEL1, SEL2 and OE signals determine which byte is output and whether or not the output bus is in the high- Z state. In the HCTL- 20XX-XX, the data latch is 32 bit wide. So, if you want to connect it directly to two microcontrollers, you are going to have to work out some scheme for them to be able to control the SEL1, SEL2 and OE signals. As others have already said, why do you want to use 2 microcontrollers? If you really must use 2 microcontrollers, I think it would probably be easiest to connect just one of them to the HCTL2032, and then provide a serial link between the 2 controllers so that the other could obtain its required data? |
