RDY
C
[RDY] External ready input. The pin has this function when
external ready input is enabled.
P80
[P80] General purpose input/output port. The pin has this
function when external ready input is disabled.

314
BGRNT
C
[BGRNT] Acknowledge output for external bus release.
Outputs "L" when the external bus is released. The pin has this
function when output is enabled.
P81
[P81] General purpose input/output port. The pin has this
function when output is disabled for external bus release
acknowledge.
164
315
BRQ
C
[BRQ] External bus release request input. Input "1" to request
release of the external bus. The pin has this function when
input is enabled.
P82
[P82] General purpose input/output port. The pin has this
function when the external bus release request input is
disabled.
310
EX_BGRNT
J
Acknowledge output for external bus release. Outputs "L"
when the external bus is released.
*
311
EX_BRQ
K
External bus release request input. Input "1" to request release
of the external bus. The pin has this function when input is
enabled.

165
316
RD
C[RD] External bus read strobe output.
166
317
WR0/UUB
C
[WR0] External bus write strobe output. When WR is used as
the write strobe, this becomes the byte-enable pin (UUB).
167
318
WR1/ULB
C
[WR1] External bus write strobe output. The pin has this
function when WR1 output is enabled. When WR is used as
the write strobe, this becomes the byte-enable pin (ULB).
P85
[P85] General purpose input/output port. The pin has this
function when the external bus write-enable output is disabled.
319
WR2/LUB
C
[WR2] External bus write strobe output. The pin has this
function when WR2 output is enabled. When WR is used as
the write strobe, this becomes the byte-enable pin (LUB).
*
P86
[P86] General purpose input/output port. The pin has this
function when the external bus write-enable output is disabled.
*
320
WR3/LLB
C
[WR3] External bus write strobe output. The pin has this
function when WR3 output is enabled. When WR is used as
the write strobe, this becomes the byte-enable pin (LLB).
*
P87
[P87] General purpose input/output port. The pin has this
function when the external bus write-enable output is disabled.
