PRELIMINARY and CONFIDENTIAL
(1) TRST, S, XRST are changed from “Low” to “High” levels in this order:
TRST
S
XRST
More than 500ns
More than 500ns
300µs
Immediately after power-on, input the “Low” level to the TRST pin for 500 ns or more. After the TRST
pin is set to “High” level, input the “Low” level to the S pin for 500 ns or more. After the S pin is set to
“High” level, input the “Low” level to the XRST pin for 300 µs or more.
(2) S is changed from “Low” to “High” levels and then TRST and XRST are changed from “Low” to “High”
levels simultaneously (TRST = XRST is possible):
S
TRST
XRST
More than 500ns
300µs
Immediately after power-on, input the “Low” level to the S pin for 500 ns or more. After the S pin is
set to “High” level, input the “Low” level to the TRST and XRST pins for 300 µs or more.
There is no restriction on the input sequence to the XRST and TRST pins.
(3) S and TRST are changed from “Low” to “High” levels simultaneously and then XRST is changed from
“Low” to “High” levels (S = TRST is possible):
S
TRST
XRST
More than 500ns
300µs
Immediately after power-on, input the “Low” level to the S and TRST pins for 500 ns or more. After
the S and TRST pins are set to “High” level, input the “Low” level to the XRST pin for 300 µs or more.
There is no restriction on the input sequence to the S and TRST pins.
