Enumeration Type Documentation

jo_time_memory_address

enum jo_time_memory_address

Enumerator
RegisterHighFRC	High Free Running Counter Register (FCR), counts up to 255, then iterates FCR Low.
RegisterLowFRC	Low Free Running Counter Register (FCR), increases every time FCR high reaches 256.
RegisterTCR	Time Control Register (TCR).
RegisterSysClock	System clock register.
