Table 11. Coefficient Select Functions of Register (WR3) (Continued)
Table 12. Gain Control Register (WR9)
WR9—Gain Control Register
The EMDP has improved performance on loops with low noise. If it is desired to take full
advantage of this improved performance capability, set register WR9 to 0Fh after reset and before
activation.
WR10-WR14—Activation Sub-State Timer Registers
The EMDP allows the user to program each of the timers in the activation state machine. This
capability allows the user to optimize the timers for operation at various data rates in a particular
application.
WR15—Micro-interruption Timer Register
The EMDP allows the user to set an expiration value for the Micro-Interruption Timer (MIT). The
EMDP stays in the ‘time out’ state until the MIT expires. The MIT is a 19 bit counter. Only 8 Most
Significant Bits (MSB) of the MIT are accessible through MITR for programing as shown in
13. (The MIT functions by counting baud periods until the value stored in MIT register is
exceeded). For further details, refer to
