COM1DIV0 Register
Name:
Address:
Default Value:
Access:
COM1DIV0 is a low byte divisor latch for UART1. COM1TX,
COM1RX, and COM1DIV0 share the same address location.
COM1TX and COM1RX can be accessed when Bit 7 in
COM1CON0 register is cleared. COM1DIV0 can be accessed
when Bit 7 of COM1CON0 is set.
COM0IEN0 Register
Name:
Address:
Default Value:
Access:
COM0IEN0 is the interrupt enable register for UART0.
COM1IEN0 Register
Name:
Address:
Default Value:

Description
Reserved.
Modem status interrupt enable bit.
Set by the user to enable generation of an
interrupt if any of COMXSTA1[3:1] are set.
Cleared by the user.
Rx status interrupt enable bit.
Set by the user to enable generation of an
interrupt if any of COMxSTA0[3:0] are set.
Cleared by the user.
Enable transmit buffer empty interrupt.
Set by the user to enable interrupt when the
buffer is empty during a transmission.
Cleared by the user.
Enable receive buffer full interrupt.
In non-FIFO mode, set by the user to enable
an interrupt when buffer is full during a
reception. Cleared by the user.
In FIFO mode, set by the user to enable an
interrupt when trigger level is reached. It also
controls the character receive timeout
interrupt. Cleared by the user.
