The flash provides a High Speed Read Mode, offering slightly higher flash read speed at the
cost of higher power consumption. Two dedicated commands, High Speed Read Mode Enable
(HSEN) and High Speed Read Mode Disable (HSDIS) control the speed mode. The High Speed

reset, the High Speed Mode is disabled, and must be manually enabled if the user wants to.
