Help on PWM signals on HC908QY4 chip

Hello.  I need to generate a PWM signal from the HC908QY4 chip, however, I've already used all the ADC pins except the PTA0 pin.  It says in the datasheet that for buffered PWM operation, to set the MS0B pin, however, I was wondering if this was necessary to generate the PWM signal since I'm already using the PTA1(TCH1) pin for other things.  Can PWM signals be generated from the TCLK pin as well and will the PWM timer signal mess up just a free-running timing counter that I may have going on as well because of the TOF register?
I'd appreciate any help I can get.
