Figure 9-35: Timer E Capture Operation: 32-Bit Cascade Operation Mode

(When CMSEmn Register's TB1Ex Bit = 1, TB0Ex Bit = 1, CCSEx Bit = 0, LNKEx Bit = 0,
BFEEx Bit = Arbitrary, EEVEx Bit = 1, and CSCEn Register's SEVEx Bit = 0)

Notes:
1. TBASE1n performs count operation when, in the 32-bit mode, CASC (CNT = MAX. for
TBASE0n) is input to TBASE1n and the rising edge of CTC is detected.
2. If an event occurs during this timing, it is ignored.
3. CPU read access is not performed in this timing (wait status).
