HICR. XBS channel 2 and the &65 pin can be used when CS2E = 1. When CS2E = 1, &65
is used when FGA20E =0, and (&65 is used when FGA20E = 1. In this manual, both are
referred to as &65.

Function
Host interface read signal
Host interface write signal
Host interface chip select signal for IDR_1,
ODR_1, STR_1
Host interface chip select signal for IDR_2,
ODR_2, STR_2
Host interface chip select signal for IDR_3,
ODR_3, STR_3
Host interface chip select signal for IDR_4,
ODR_4, STR_4
In host read access, this signal selects the
status registers (STR_1 to STR_4) or data
registers (ODR_1 to ODR_4). In host write
access to the data registers (IDR_1 to
IDR_4), this signal indicates whether the
host is writing a command or data.
