Rev. 1.4
Pins CMDVCC%, CMDVCC#, CS,
Pins RSTIN, CLKIN, PRES, EXT_RST have the pull-down enabled.
Pin OFF_ACK has a 100kΩ resistor connected to pin OFF_REQ internally.
Strong PFET or NFET is approximately 100
Very strong PFET or NFET is approximately 50
Medium strength PFET is approximately 1k
Very weak PFET or NFET is approximately 1M
The diodes represent ESD protection devices that will conduct current if forward biased.
