SYSCLK
C
[SYSCLK] System clock output. The pin has this function when
system clock output is enabled. This outputs the same clock as the
external bus operating frequency. (Output halts in stop mode.)
P90
[P90] General purpose input/output port. The pin has this function
when system clock output is disabled.
170
323
P91
C
[P91] General purpose input/output port.
171
325
MCLK
C
[MCLK] Memory clock output. The pin has this function when
memory clock output is enabled. This outputs the same clock as
the external bus operating frequency. (Output halts in sleep
mode.)
P92
[P92] General purpose input/output port. The pin has this function
when memory clock output is disabled.
172
326
P93
C
[P93] General purpose input/output port.
173
327
AS
C
[AS] Address strobe output. The pin has this function when ad-
dress strobe output is enabled.
LBA
[LBA] Address strobe output for burst flash ROM. The pin has this
function when address strobe output is enabled.
P94
[P94] General purpose input/output port. The pin has this function
when address strobe output is disabled.
174
328
BAA
C
[BAA] Address advance output for burst Flash ROM. The pin has
this function when address advance output is enabled.
P95
[P95] General purpose input/output port. The pin has this function
when address advance output is disabled.
175
329
P96
C
[P96] General purpose input/output port.
176
330
WR
C
[WR] Memory write strobe output. The pin has this function when
write strobe output is enabled.
P97
[P97] General purpose input/output port. The pin has this function
when write strobe output is disabled.
