Trip Zone input 2 (I)

McBSP-B receive serial data (I)
General purpose input/output 14 (I/O/Z)
(5)
Trip Zone input 3/External Hold Request. XHOLD, when active (low), requests the external interface
(XINTF) to release the external bus and place all buses and strobes into a high-impedance state.
To prevent this from happening when TZ3 signal goes active, disable this function by writing
XINTCNF2[HOLD] = 1. If this is not done, the XINTF bus will go into high impedance anytime TZ3
goes low. On the ePWM side, TZn signals are ignored by default, unless they are enabled by the
code. The XINTF will release the bus when any current access is complete and there are no
pending accesses on the XINTF. (I)
SCI-B Transmit (I)
McBSP-B transmit clock (I/O)
General purpose input/output 15 (I/O/Z)
(5)
Trip Zone input 4/External Hold Acknowledge. The pin function for this option is based on the
direction chosen in the GPADIR register. If the pin is configured as an input, then TZ4 function is
chosen. If the pin is configured as an output, then XHOLDA function is chosen. XHOLDA is driven
active (low) when the XINTF has granted an XHOLD request. All XINTF buses and strobe signals
will be in a high-impedance state. XHOLDA is released when the XHOLD signal is released.
External devices should only drive the external bus when XHOLDA is active (low). (I/0)
