LDC function is independent of the other Control Bit

Normal Operation

FRC

R-Counter Value

Description

× R_cnt value (OSCI / 8 × R),

Use 13 bits R-Counter

FRC function is independent of the other Control Bit

R-cnt value (OSC / R),

Use 15 bits R-Counter

Description

Normal

• FRC is independent of the other control bit

• Test is internal register control bit

but, Test is external control pin

• Test is related with Test,

when Test = High

→ Test Mode
