USART
Device Oscillator
Parallel Slave Port
The original USART/SCI module that was offered on Midrange devices specified a “high speed”
mode (when the BRGH control bit is set). Due to the design of the sampling circuitry, the opera-
tion of this mode was not as robust as desired. The sampling circuitry has been changed so that
operation now meets Microchip’s requirements. The difference in the sampling is described in the
“USART”
Table C-5:
A new mode has been added into the device oscillator which allows the device to operate from
an internal RC. This is specified at time of device programming (configuration word). This mode
will be included on many future devices. See the device data sheets configuration word to deter-
mine if the device supports this mode.
The control pins have changed from level sensitive to edge sensitive.
