This pin function is used to select the operating mode during reset. The
TMP1940CYAF enters NORMAL mode when this pin is sampled high at the rising
edge of RESET . This pin should not be pulled up to a logic 1 during a reset sequence.
With the TMP1940FDBF, which has an on-chip flash, this pin is used to put the flash in
Single-Boot mode. For details, refer to the TMP1940FDBF datasheet pages.
Port 86: Programmable as input or output
16-Bit Timer 3 Output: Output from 16-bit Timer 3
Interleave Mode: This pin function is used by the TMP1940FDBF with the on-chip
flash. The TMP1940FDBF enters Interleave mode when this pin is sampled high at the
rising edge of RESET . During a reset sequence, this pin should be pulled up to a logic
1 when Interleave mode is used and pulled down to a logic 0 otherwise. For a
description of when Interleave mode is required, refer to the TMP1940FDBF datasheet
pages.
Port 87: Programmable as input or output
This pin is used to select the operating mode during reset. This pin should be pulled
down to a logic 0 during a reset sequence.
Port 90: Programmable as input or output
Serial Transmit Data 0: Programmable as a push-pull or open-drain output
Port 91: Programmable as input or output
Serial Receive Data 0
