28x2 serrxd question


Senior Member
Just a quickie question on serrxd on x2 chips.

The manual is not clear what happens to baudrate with different clock speeds. Unlike non x2's where it is clearly shown.

Anybody got any ideas?

Same for all PICAXE chips; double the clock frequency and the baud rate doubles.

Ok, then why does the manual say -

'Effect of Increased Clock Speed
Increasing the clock speed increases the serial baud rate as shown below (non X2 parts).

Or is it just an "error".

Basically I want to capture incoming serial data at 9600 baud (inverted, which would be N9600_X on an M2 using normal I/O pin).
So do I have to setfreq M8 to enable that on an X2.
