Read/Write
This 8-bit register controls the operation of the UART in conjunction with COMCON1.
Description
Divisor latch access
Set by user to enable access to COMDIV0 and COMDIV1 registers
Cleared by user to disable access to COMDIV0 and COMDIV1 and enable access to COMRX, COMTX and
COMIEN0
Set break.
Set by user to force TXD to 0
Cleared to operate in normal mode
Stick parity
Set by user to force parity to defined values:
1 if EPS = 1 and PEN = 1
0 if EPS = 0 and PEN = 1
Even parity select bit
Set for even parity
Cleared for odd parity
Parity enable bit:
Set by user to transmit and check the parity bit
Cleared by user for no parity transmission or checking
Stop bit
Set by user to transmit 1.5 Stop bit if the Word Length is 5 bits or 2 Stop bits if the word length is 6, 7 or 8
bits. The receiver checks the first Stop bit only, regardless of the number of Stop bits selected
Cleared by user to generate 1 Stop bit in the transmitted data
Word length select:
00 = 5 bits
01 = 6 bits
10 = 7 bits
11 = 8 bits
