8/16-Bit Composite Timer 00/01 Control Status Register 0 (T00Cr0/T01Cr0) - Fujitsu F2MC-8FX Hardware Manual

CHAPTER 16 8/16-BIT COMPOSITE TIMER
16.5.1 8/16-bit Composite Timer 00/01 Control Status Register 0
(T00CR0/T01CR0)
The 8/16-bit composite timer 00/01 control status register 0 (T00CR0/T01CR0) selects the
timer operation mode, selects the count clock, and enables or disables IF flag interrupts.
The T00CR0 and T01CR0 registers correspond to timers 00 and 01, respectively.
