Processor Module and Device Adapter Specification

5.8

DVA17XXXX0

These device adapters are intended for use with

PICmicro MCU devices supported by the PCM17XA0

processor module. In all processors in EC mode,

OSC/4 is not supported. OSC/4 in EC mode is

supported in DVA17XXXX1 device adapters.

5.9

Emulating a .600 28-Pin Part

When emulating a .600 wide, 28-pin device, an adapter

will be needed to convert the standard .300 wide

socket on the device adapters to the .600 wide socket

on the target board.

There are many adapters available for this purpose,

such as Digi-Key part number A502-ND.

5.10

T1OSC Jumper

Some device adapters are equipped with a 3-pin

jumper to force the device adapter to enable/disable

the Timer1 oscillator circuitry.

When in the “ON” position, the device adapter’s Timer1

oscillator circuitry is always enabled regardless of the

T1OSCEN bit in T1CON.

When in the “OFF” position, the device adapter’s

Timer1 oscillator circuit is enabled/disabled by software

in application code by the T1OSCEN bit in T1CON.

Note:

PCM16XB0/B1, PCM16XE0/E1,

PCM16XK0 and PCM16XL0 do not

support software enable/disable of the

Timer1 circuitry and must use the jumper

to either enable or disable the function (see

Table 5-7 for DVA16XP282, DVA16XP401,

DVA16XL441 and DVA16PQ441).
