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).
