14.2
14.2.1
SYSCR is an 8-bit read/write register which controls chip operations. Host interface functions are
enabled or disabled by the HIE bit of SYSCR. See section 3.2, System Control Register, for
information on other SYSCR bits. SYSCR is initialized to H'09 by an external reset and in
hardware standby mode.
Bit 1—Host Interface Enable (HIE): Enables or disables the host interface. When enabled, the
host interface handles host-slave data transfers, operating in slave mode.
