EN_PULSE
Description
When set, this bit enables auto busy status when the host
sets reset. The busy status remains present until the internal
time-out or when using a µP and the µP clears the busy
status. When cleared, this bit disables auto busy on host
resets. The pulse time for busy is 2(15)/PC_MCLK (MHz)
= SEL.
