CCS/MSP430FR5994: Error Setting Multiple Timer Frequencies

Tool/software: Code Composer Studio

I am trying to generate multiple frequencies from timer interrupts (to flash LEDs at different rates, etc.) using Multiple Time Bases similar to the two links below.

e2e.ti.com/.../1165370

However, when I try to set "TA0CCTL3" and "TA0CCR3" (and 4/5/6, not shown here) I get the following errors.

"../main.c", line 263: error #20: identifier "TA0CCTL3" is undefined
"../main.c", line 264: error #20: identifier "TA0CCR3" is undefined

With the MSP430FR5994 (on the MSP-EXP430FR5994 Development Kit) I should be able to define up to TA0CCR6. Any suggestions why this is not working?

Here is my code to configure the timers. I also use #include <msp430.h> in the code.

    TA0CTL |= TASSEL_1;             // Use ACLK as source
    TA0CTL |= ID_0;                 // Divide clock by 1
    TA0CTL |= MC_2;                 // Use CONTINUOUS mode timer
    TA0CTL |= TACLR;                // Clear timer

    TA0CCTL0 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR0 = 5000;                 // Number of cycles in the timer

    TA0CCTL1 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR1 = 10000;                // Number of cycles in the timer

    TA0CCTL2 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR2 = 15000;                // Number of cycles in the timer

/*
These two lines create errors - TA0CCTL3 and TA0CCR3 are undefined.
See Table 25-8 in slau367o.pdf - should be able to define 7 counters.
*/

    TA0CCTL3 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR3 = 20000;  		    // Number of cycles in the timer

    TA0IV = 0x0000;                 // Clear the interrupt flag
