N (see the Using the Fractional Divider section).
Network Addressable UART Mode
This mode allows connecting the MicroConverter on a 256-node
serial network, either as a hardware single master or via software
in a multimaster network. Bit 7 of COMxIEN1 (ENAM bit)
must be set to enable UART in network-addressable mode.
Note that there is no parity check in this mode. The parity bit is
used for address.
Network Addressable UART Register Definitions
Four additional registers, COMxIEN0, COMxIEN1, COMxIID1,
and COMxADR are used only in network addressable UART
mode.
In network address mode, the least significant bit of the
COMxIEN1 register is the transmitted network address control
bit. If set to 1, the device is transmitting an address. If cleared
to 0, the device is transmitting data. For example, the following
master-based code transmits the slave address followed by the data:
COM0IEN1
= 0xE7;
//Setting ENAM, E9BT, E9BR, ETD, NABP
COM0TX = 0xA0;
// Slave address is 0xA0
while(!(0x020==(COM0STA0 & 0x020))){} // wait for adr tx to finish.
COM0IEN1
= 0xE6;
//
Clear NAB bit to indicate Data is coming
COM0TX = 0x55;
// Tx data to slave: 0x55
