Table 10. GPIO Data Register
Modem Reset
The Modem Reset signal, MRESET, is used to reset an optional socket
modem. This signal is controlled by bit 5 in the register shown in
The MRESET signal is available at the embedded modem socket inter-
face (J9, Pin 1). Setting this bit Low places the optional socket modem into
a reset state. You must pull this bit High again to enable the socket modem.
Reference the appropriate documentation for the socket modem to reset
timing requirements.
User Triggers
Two trigger output pins are provided on the eZ80Acclaim!
Kit. Labeled J21 (Trig2) and J22 (Trig1), these pins allow you to trigger
external equipment to aid in the debug of the system. See
trigger pin details.
