MC92604 Dual GEt Design Verification Board User’s Guide, Rev. 1

Freescale Semiconductor

4-3

4.1.2

Test Setup for Half-Speed Modes

Serial link testing may also be performed using half-speed mode (HSE = ‘1’). This reduces all frequencies 
in the setup by a factor of two. 

Figure 4-2

 depicts the serial link test setup using HSE and a divide-by-10 

prescaler. The control bits are set as follows:

•

HSE  =  ‘1’

•

REPE  =  ‘1’

•

TBIE  =  ‘1’

All other control bits are set to ‘0,’ except RESET, which is initially set to ‘0,’ then transitioned to ‘1’ to 
start the MC92604.
