Problems with the GATE function.

Hello: I have several problems with the routines that use hardware resources, IRQs and GATE, with the AT89LP214 controller, I made a small program in the assembler that generates a square wave with 2-bit output from port 1, activate the GATE0-1 function to control the timers from INT0-1, what happens is that it does not inhibit the outputs independently, the INT1 bit, when I set it to negative, inhibits both timers, having to inhibit only timer 1. Do any of you have difficulties with include files in terms of the hardware and software functions that I mention? Thanks and waiting for an answer, best regards.
