The CVM5XXM Member module emulates the 14-pin PIC16C505 and the 8-pin PIC12C508,

PIC12C509, PIC12CE518, and PIC12CE519 micro-controllers. These devices are part of the 12

bit PICmicro family and therefore requires the 5X FAMILY module (CVM5XF) for operation.

The PIC12CE518 and PIC12CE519 devices have EEPROM support.

EMULATOR DISCREPENCIES:

Due to BONDOUT limitations, the following features are either NOT SUPPORTED or are

modified slightly:

! The Wake-Up on pin change feature is not supported. The GPWU bit (OPTION.7) has no

! The “weak pull-up” resistors are enabled/disabled by hardware jumpers on the member pod

! Mathias provides the operating clock so the OSCCAL register has no affect. You can

! GP3 is an INPUT ONLY on the real device to accommodate that pin’s alternative use as

! In an actual device, setting the TOCS bit (OPTION.5) automatically forces GP2 to be an

! In an actual device, GPIO bits 6 and 7 are not implemented and will always read back ‘0’. In

! EEPROM support for PIC12CE518 and PIC12CE519 devices are available on RA0 for SDA

read FLOATING inputs and their value is indeterminate.
