Specifications & Instructions

Command Byte

The operation of the MS2100 is controlled by the data received into the SPI port. The command byte

syntax is as follows:

PS0

ODIR

MOT

ASI

ASO

DHST – High Speed Oscillator Test

When high, the internal high speed clock is set to drive the DHST pad at ½ the clock speed.

When low, the DHST pad is set to DVDD. This is used for debug purposes only, and will not be

set in normal operation.

PS0, PS1, and PS2 – Period Select

Selects the division ratio applied to the L/R oscillator output to set the period being measured.

ODIR – Oscillator Direction

Determines the magnetic oscillator direction if MOT is set to 1. It has no effect on direction when

the MOT bit is set to zero. This is used for debug purposes only, and will not be set in normal

operation.

MOT – Magnetic Oscillator Test

When set, causes the magnetic oscillator selected by AS0 and AS1 in the directions

selected by ODIR to run continuously until MS2100 is reset.
