This device adapter is intended for use with PIC16F716

18-pin DIP devices. It has a second oscillator device that

allows TIMER1 oscillator input ranging from 32-40 kHz. It

has four mechanical switches. Target pins RB1 and RB2

can be routed to the emulator silicon on the PCM16YJ0

processor module or the TIMER1 oscillator device on the

device adapter. Target pin RB1 is routed to T1CKI. Target

pin RB3 can be a general purpose input or CCP1, as shown

in Table 5-5.

devices

supported

the

PCM16XB0/B1,

PCM16XE0/E1, PCM16XK0 and the PCM16XL0 processor

modules. The device adapters have a second oscillator

device that allows TIMER1 oscillator input ranging from 32

to 40 kHz.

For PCM16XB0/B1, PCM16XE0/E1, PCM16XK0 and

PCM16XL0, configure jumper J1 per Table 5-7.

For all other processor modules supported by these device

adapters, leave the jumper on pins 1-2 (OFF); the Timer1

oscillator enable/disable function is software configurable.

Results

TIMER1 Oscillator Input enabled

Short J1 pins 2-3 (ON)

RC0/T1OSO/T1CKI pin = T1OSO

RC1/T1OSI/CCP2 pin = T1OSI

TIMER1 Oscillator Input disabled

Short J1 pins 1-2 (OFF)

RC0/T1OSO/T1CKI pin = RC0 or T1CKI

RC1/T1OSI/CCP2 pin = RC1 or CCP2
