Therefore, the pulse rate register is programmed to

be :

To improve the accuracy, either gain register can

be programmed to correct for the round-off error in

PR. This value would be calculated as

To allow for a simpler interface in a multi-phase

system, the EOUT and EDIR pins can be connected

together and used in a wired-or configuration. The

parts must be driven with the same clock and pro-

grammed with different phases (PH[1:0] in the

Configuration register). The pulse width and the

pulse separation is an integer multiple of system

clocks (approximately equal to 1/8 of the period of

the contents of the pulse-rate register). The maxi-

mum frequency is therefore MCLK/K/8. A timing

diagram for a multi-phase system is shown in Fig-

ure 8.
