Hi guys

The IOC options on this chip are very good , with both neg/ pos trig selection on most of the ports

The dt_int18-34c currently does not appear the clear IOCxF bits after being trigger even if the flagreset is set
Code:
ASM
INT_LIST macro; IntSource,  Label     , Type, ResetFlag?
    INT_Handler  IOC_INT, _Rx_mode_IOC ,  PBP, yes      ; Call Rx_mode_IOC subroutine for RF RX_mode
    
 endm
 INT_CREATE								; Creates the Interrupt Processor
ENDASM
also enable/disable of IOC " @ INT_DISABLE IOC_INT " ( PIE0.4 = 0) , will not stop the IOC interrupt being set on the IOCxF

the triggered IOC port flag bit needs to be cleared after the interrupt is serviced - eg IOCxF.x = 0

this what i found for my 27k40 silicon 0 ,

but if i am wrong please check and correct me

cheers

Sheldon
