17.1.2
17.1.3
Tables 64 to 79 describe the bit functions of each of the Master Control Registers in the MT9072. Each register is
repeated for each of the 8 framers. Framer 0 is addressed with Y=0, Framer 1 with Y=1, Framer 2 with Y=2,...
Framer 7 with Y=7 (where Y represents the 4 most significant address bits (MSB) A
simultaneous write to all 8 Framers is possible by setting the address A11 to 1 and A10 to A8 to 0. A (0), (1) or (#)
in the “Name” column of these tables indicates the state of the data bits after a hard reset (the RESET pin is toggled
from zero to one), or a software reset (the RST bit in control register address YF1 is toggled from one to zero or
toggling of RSTC in Global Control Register). The (#) indicates that a (0) or (1) is possible.
xxxx indicates all (0000 to 1111) binary possibilities
X indicates all (0 to F) hex possibilities
yyyy indicates 9 (000, 001, 010, 011, 111,1000,1001) binary possibilities representing 1 of 8 framers (R/W), and
all 8 framers (W only) and global selection.
Y indicates 9 (0,1,2,3,4...9) hex possibilities representing 1 of 8 framers (R/W), and all 8 framers (W only) and
global selection.
