I am trying to do 8 data bits with even parity, if i use the program below it works fine when i work with 7 data bits and even parity but seems to fail as soon as i go to 8 bits with parity, any suggestions

CMCON = %00000111 ;Disable Comparator module's
OPTION_REG = %11010111 ;Set PIC options
INTCON = 0 ;Disable interrupts
TRISB = %00000010 ;RB1(RX) as input, others to Output
TRISA = 255 ;SET PORTA AS INPUTS

DEFINE OSC 8 ; set oscilator speed to 8mHz
DEFINE HSER_RCSTA 90h ; Enable serial port & continuous receive
DEFINE HSER_TXSTA 20h ; Enable transmit, BRGH = 1
DEFINE HSER_SPBRG 12 ; 9600 Baud @ 8MHz, 0.16%
DEFINE HSER_CLROERR 1 ; Clear overflow automatically
DEFINE HSER_BITS 9
DEFINE HSER_EVEN 1

PORTB.4 = 1
DATAIN VAR BYTE[8]
loop
HSERIN [str DATAIN\8]
HSEROUT [str DATAIN\8]
goto looP
END
