TMRx_CAPA_H
00h–FFh These bits represent the High byte of the 2-byte capture
value, {TMRx_CAPA_H[7:0], TMRx_CAPA_L[7:0]}. Bit 7
is bit 15 (msb) of the 16-bit data value. Bit 0 is bit 8 of the
16-bit timer data value.
Timer Input Capture Value B Register—Low Byte
The Timer x Input Capture Value B Register—Low Byte, detailed in Table 64,
stores the Low byte of the capture value for external input B. For Timer 1, the
external input is IC1. For Timer 3, it is IC3.

TMRx_CAPB_L
00h–FFh These bits represent the Low byte of the 2-byte capture
value, {TMRx_CAPB_H[7:0], TMRx_CAPB_L[7:0]}. Bit 7
is bit 7 of the 16-bit data value. Bit 0 is bit 0 (lsb) of the 16-
bit timer data value.
