This register holds the higher 4 bits of the timer. While writing into the 12-bit reload register, write the lower byte first then the higher
nibble.

Timer Capture
Cypress enCoRe II has two 8-bit captures. Each capture has separate registers for the rising and falling time. The two eight bit captures
can be configured as a single 16-bit capture. When configured, the capture 1 registers hold the high order byte of the 16-bit timer
capture value. Each of the four capture registers may be programmed to generate an interrupt when it is loaded.
