Resource Usage
The I2C routines utilize the I/O Timer to regulate the bit timing for channels 1-4.  While sending or
receiving I2C data, the corresponding timer busy flag will be True indicating that the I/O Timer is in use. 
On the ZX-24n, ZX-24p, ZX-24r and ZX-24s, the hardware I2C channel cannot be used while Com2 is
open since pin 11 is shared by the SDA signal and TxD for Com2.
Compatibility
This subroutine is not available in BasicX compatibility mode.
