Comments
The nibbles are
mirrored so that
LSB- or MSB-first
mode registers
correctly, regard-
less of shift mode
Unique chip ID
used to differ-
entiate devices;
read only
Unique speed
grade ID used to
differentiate
devices; read

Bits are set to
determine which
device on chip
receives the next
write command;
the default is all
devices on chip
Synchronously
transfers data
from the master
shift register to
the slave
Determines
various generic
modes of chip
operation
The divide ratio is
the value plus 1
