11.3 Register Descriptions
Time V has the following registers.
• Timer counter V (TCNTV)
• Timer constant register A (TCORA)
• Timer constant register B (TCORB)
• Timer control register V0 (TCRV0)
• Timer control/status register V (TCSRV)
• Timer control register V1 (TCRV1)
11.3.1 Timer Counter V (TCNTV)
TCNTV is an 8-bit up-counter. The clock source is selected by bits CKS2 to CKS0 in timer
control register V0 (TCRV0). The TCNTV value can be read and written by the CPU at any time.
TCNTV can be cleared by an external reset input signal, or by compare match A or B. The
clearing signal is selected by bits CCLR1 and CCLR0 in TCRV0.
When TCNTV overflows, OVF is set to 1 in timer control/status register V (TCSRV).
TCNTV is initialized to H'00.
