MCF5441x Tower Module Elevator Connections A34 and A35 (SR 1-1292701868)

The MCF5441x Tower Module User Manual v1.1 (http://cache.freescale.com/files/netcomm/doc/user_guide/TWRMCF5441XUM.pdf) lists the following connections:

Pin Name Group Usage                Used

A33 TMR1 Timer PD1/RGPIO/T2IN/T2OUT X

A34 TMR0 Timer PD0/RGPIO/T1IN/T1OUT X

 

After trying to use the pins, it appears that neither is what they are documented as.

 

A33 appears to be PD0/T1IN.  I have verified this both using the pin configured as GPIO and as T1IN.

 

I had hoped that A34 was PD1/T2IN (i.e the pins were just criss-crossed) but it doesn't appear to function as GPIO D1 or as T2IN.  Doesn't appear to work as the other GPIO or TxINs for the group  "DMA Timers".

 

Does anyone know what A34 might be or have an updated user manual for this kit?
