Pin change interrupt on ATTINY4313

I am using Bascom 2.0.7.6 and attempting to use pin change interrupts on an ATTINY4313 for use with an encoder. Looking at the .DAT file for this chip, it looks like the correct pin change interrupt would be PCINTD and, although it does not show up in red in the editor, it works correctly for the ON PCINTD command, it does not work for the enable PCINTD command. I was able to get the interrupts to work by setting the correct bit but was wondering if I was doing something wrong if there is a problem with the .DAT file? Here's the relevant code:

Why Pcintd?
Try PCINT2 instead.

Well, because when I tried PCINT2, I get an error message that says "unknown interrupt source".

Sorry, I just now took a look at the ATtiny4313.dat file.
At least in my version of Bascom (2.0.7.6) all of the options are missing and the intlist is as it seems not complete.
Just compare with ATtiny2313A.dat file (memory is different there).
You best write an email to Bascom Support for a correction request.

there was a typo in the bit name.
just replace the intlist section for this one :

[INTLIST]
count=20
INTname1=INT0,$001,GIMSK.INT0,EIFR.INTF0
INTname2=INT1,$002,GIMSK.INT1,EIFR.INTF1
INTname3=ICP1@CAPTURE1,$003,TIMSK.ICIE1,TIFR.ICF1
INTname4=OC1A@COMPARE1A,$004,TIMSK.OCIE1A,TIFR.OCF1A
INTname5=OVF1@TIMER1,$005,TIMSK.TOIE1,TIFR.TOV1
INTname6=OVF0@TIMER0,$006,TIMSK.TOIE0,TIFR.TOV0
INTname7=URXC@SERIAL,$007,UCSRB.RXCIE,UCSRA.RXC
INTname8=UDRE,$008,UCSRB.UDRIE,UCSRA.UDRE
INTname9=UTXC,$009,UCSRB.TXCIE,UCSRA.TXC
INTname10=ACI,$00a,ACSR.ACIE,ACSR.ACI
INTname11=PCINT0@PCINTB,$00B,GIMSK.PCIE0,EIFR.PCIF0
INTname12=OC1B@COMPARE1B,$00C,TIMSK.OCIE1B,TIFR.OCF1B
INTname13=OC0A@COMPARE0A,$00D,TIMSK.OCIE0A,TIFR.OCF0A
INTname14=OC0B@COMPARE0B,$00E,TIMSK.OCIE0B,TIFR.OCF0B
INTname15=USI_START,$00F,USICR.USISIE,USISR.USISIF
INTname16=USI_OVF,$010,USICR.USIOIE,USISR.USIOIF
INTname17=EERDY,$011,EECR.EERIE
INTname18=WDT@WATCHDOG,$012,WDTCR.WDIE,WDTCR.WDIF
INTname19=PCINT1@PCINTA,$013,GIMSK.PCIE1,EIFR.PCIF1
INTname20=PCINT2@PCINTD,$014,GIMSK.PCIE2,EIFR.PCIF2

atmel started to use PCINTA, B etc. instead of the PCINT0, 1 , 2 etc. The PCINTA makes sense indeed but only when all pins are on the same port.

I'm building an external int. using PortB 6 & 7 driving an encoder. I see the PCINTB is now working but there seems to be no place for the mask to select the ports. I tried assembly but it doesn't recognize the PCMSK0 for the 2313a tiny:

Bascom 2.077

$regfile = "attiny2313a.dat"

.

.

!ldi r16,$60
!out PCMSK0,r16

Thanks for the time and help,
Rob

for tiny2313A, atmel uses pcmsk, pcmsk1 and pcmsk2. So there is no pcmsk0.
so use :
pcmsk=&H60
