20.9 Electrical characteristics

Except for “Icc,” the electrical characteristics of the M37733S4BFP are the same as those of the

M37733MHBXXXFP in the microprocessor mode. For the others, refer to chapter “15. ELECTRICAL

CHARACTERISTICS.”)

connected to

Vss.

Notes 1: This is applied when the main clock external input selection bit = “1,” the main clock division

selection bit = “0,” and the signal output disable selection bit = “1.”

2: This is applied when the main clock external input selection bit = “1” and the system clock stop

selection bit at wait state = “1.”

3: This is applied when CPU and the clock timer are operating with the sub clock (32.768 kHz)

selected as the system clock.

4: This is applied when the XCOUT drivability selection bit = “0” and the system clock stop bit at wait

state = “1.”
