LTC1090
1090fc
Motorola SPI (MC68HC05C4)
The MC68HC05C4 transfers data MSB first and in 8-bit
increments. Programming the LTC1090 for MSB first
format and 16-bit word length allows the 10-bit data
output to be received by the MPU as two 8-bit bytes with
the final 6 unused bits filled with zeroes by the LTC1090.
Hardware and Software Interface to Motorola MC68HC05C4
Processor
Hitachi Synchronous SCI (HD63705)
The HD63705 transfers serial data in 8-bit increments,
LSB first. To accommodate this, the LTC1090 is
programmed for 16-bit word length and LSB first format.
The 10-bit output data is received by the processor as two
8-bit bytes, LSB first. The LTC1090 fills the final 6 unused
bits (after the MSB) with zeroes in unipolar mode and with
the sign bit in bipolar mode.
