Register 43-27: PWMCAPx: Primary PWM Time Base Capture Register
R-0 R-0 R-0 R-0 R-0 R-0 R-0 R-0
PWMCAP<12:5>
bit 15 bit 8
R-0 R-0 R-0 R-0 R-0 U-0 U-0 U-0
PWMCAP<4:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-3 PWMCAP<12:0>: Captured PWM Time Base Value bits
The value in this register represents the captured PWM time base value when a leading edge is
detected on the current-limit input.
bit 2-0 Unimplemented: Read as ‘0
Note 1: The Capture feature is available only on primary output (PWMxH).
2: This feature is active only after the LEB processing on the current-limit input signal is complete.
3: The minimum capture resolution is 8.32 ns.
4: This feature can be used only when XPRES = 0 (PWMCONx<1>).
