DETAIL OPERATION
COMPLETE SPI OPERATION
Table 14 is a compiled view of all the SPI capabilities and
options. Both MOSI and MISO information are described.
Note: P = 0 if parity bit is not selected or parity = 0. P = 1 if parity
is selected and parity = 1.
PARITY BIT 8
Calculation
The parity is used for the write-to-register command (bit
15,14 = 01). It is calculated based on the number of logic one
contained in bits 15-9,7-0 sequence (this is the entire 16 bits
of the write command except bit 8).
Bit 8 must be set to 0 if the number of 1 is odd.
Bit 8 must be set to 1if the number of 1 is even.
Examples 1:
MOSI [bit 15-0] = 01 00 011 P 01101001, P should be 0,
because the command contains 7 bits with logic 1.
Thus the Exact command will then be:
MOSI [bit 15-0] = 01 00 011 0 01101001
Examples 2:
MOSI [bit 15-0] = 01 00 011 P 0100 0000, P should be 1,
because the command contains 4 bits with logic 1.
Thus the Exact command will then be:
MOSI [bit 15-0] = 01 00 011 1 0100 0000
Parity Function Selection
All SPI commands and examples do not use parity
functions.
The parity function is optional. It is selected by bit 6 in INIT
MISC register.
If parity function is not selected (bit 6 of INIT MISC = 0),
then Parity bits in all SPI commands (bit 8) must be “0”.
