CS4: Chip select output. This function is valid when the chip select 4
output setting is enabled.
PA4: General purpose input/output port. This function is valid when the
chip select 4 output setting is disabled.
CS5: Chip select output. This function is valid when the chip select 5
output setting is enabled.
PA5: General purpose input/output port. This function is valid when the
chip select 5 output setting is disabled.
C: Bypass capacitor pin for internal capacitor. See “HANDLING DEVIC-
ES”
CS6: Chip select output. This function is valid when the chip select 6
output setting is enabled.
PA6: General purpose input/output port. This function is valid when the
chip select 6 output setting is disabled.
CS7: Chip select output. This function is valid when the chip select 7
output setting is enabled.
PA7: General purpose input/output port. This function is valid when the
chip select 7 output setting is disabled.
RDY: External ready signal input. This function is valid when the external
ready input setting is enabled.
P80: General purpose input/output port. This function is valid when the
external ready input setting is disabled.
BGRNT: External bus open acknowledge output. This pin outputs an L
level signal when the external bus is open. This function is valid when the
output setting is enabled.
P81: General purpose input/output port. This function is valid when the
output setting is disabled.
BRQ: External bus open request input. The input value is “1” when the
external bus is open. This function is valid when the input setting is
enabled.
P82: General purpose input/output port. This function is valid when the
input setting is disabled.
External bus read strobe output.
External bus write strobe output.
UUB: Is the upper side of the 16-bit SRAM input/output mask enable
signal. It is valid when the external bus is set to SRAM use. (WE/P97
function as the write strobe.)
External bus write strobe output.
ULB: Is the lower side of the 16-bit SRAM input/output mask enable
signal. It is valid when the external bus is set to SRAM use. (WE/P97
function as the write strobe.)
P85: General purpose input/output port. This function is valid when the
enable output setting is disabled.
