Pulse-Width Modulation Falling Edge—High Byte
Writing to TMR3_PWMxF_H stores the value in a temporary holding register. A
parallel 16-bit Write of {TMR3_PWMxF_H[7–0], TMR3_PWMxF_L[7–0]} occurs
when software initiates a Write to TMR3_PWMxF_L. The register is detailed in
Table 79.

(TMR3_PWM0F_H = 0085h, TMR3_PWM1F_H = 0087h, TMR3_PWM2F_H = 0089h,
TMR3_PWM3F_H = 008Bh)

Value Description
00h–FFh These bits represent the High byte of the 16-bit value to set
the falling edge COMPARE value for PWMx,
{TMR3_PWMXF_H[7:0], TMR3_PWMXF_L[7:0]}. Bit 7 is bit
15 (msb) of the 16-bit timer data value. Bit 0 is bit 8 of the 16-
bit timer data value.
