3 Pin Information
(continued)
Functional descriptions of pins 1—100 are found in Section 6, Signal Descriptions.
*
3-states when RSTB = 0 and INT0 = 1. Output = 1 when RSTB = 0 and INT0 = 0, except CKO which is free-running.
Pull-up devices on input.
§
3-states by JTAG control.
** See Section 7, Mask-Programmable Options.
For SIO multiprocessor applications, add 5 k
external pull-up resistors to SADD1 and/or SADD2 for proper initialization.
3-states when RSTB = 0, or by JTAG control.
