//  Ver | dd mmm yyyy | Who  | Description of changes
// =====|=============|======|===============================================
//  1.00| 11 Sep 2003 | L.H. | Changes since previous version (v.58 Alpha)
//      |             |      | CAPCON, EXTCON and CAPFIFO register for EVA renamed CAPCONA
//      |             |      |    EXTCONA and CAPFIFOA.  This is to be consistant
//      |             |      |    with other documentation. EVB was already correct.
//      |             |      | Corrected bit definitions for GPTCONA & GPTCONB registers
//      |             |      | T1CON and T2CON were using the same bit definitions.  Split
//      |             |      |    this so the reserved bits in T1CON would be correct
//      |             |      | T3CON and T4CON were using the same bit definitions.  Split
//      |             |      |    this so the reserved bits in T3CON would be correct
//      |             |      | Changed QEPIQEL to QEPIQUAL in EXTCONA/EXTCONB registers
//      |             |      | Added bits that are active only when EXTCONA.0 = 1 
//      |             |      |    to the COMCONA and COMCONB registers. 
//      |             |      | Changed CAPQEPN to CAP12EN in the CAPCONA register
//      |             |      | Changed CAPQEPN to CAP45EN in the CAPCONB register
