bit is located in bit D10, and the parity is calculated using bits D15 through D11. For Write commands, the parity bit is located in
bit D9, and the parity is calculated using bits D15 through D0. If a parity error is detected, both the current and subsequent com-
mands are ignored, and the parity fault response is transmitted during the subsequent SPI transfer.

SPI Diagnostic and Programming Mode allows for the following functions:
SPI transfers follow CPOL = 0, CPHA = 0, MSB first convention.
The following operations are supported in DPM:
All commands except for the DPM Entry command employ odd parity to ensure data integrity. For Read commands, the parity
All responses except for the DPM entry response employ odd parity to ensure data integrity. Parity is calculated using the entire
