LPC Enable 3 to 1
Enable or disable the host interface function in
single-chip mode. When the host interface is enabled
(one of the three bits is set to 1), processing for data
transfer between the slave processor (this LSI) and
the host processor is performed using pins LAD3 to
LAD0, /)5$0(, /5(6(7, LCLK, SERIRQ,
&/.581, and /3&3'.
