OUT [8mA]
OUT [8mA]
Peripheral Chip Select Output (Active LOW)
These pins indicate to the system that a bus cycle is in progress to
the corresponding region of the peripheral space.
PIO5
(1)
PCS[7]#
P3
I/O [4mA]
OUT [4mA]
Peripheral Chip Select Output [4mA] (Active LOW)
This pin indicates to the system that a bus cycle is in progress to
address 0xE00 of the peripheral space.
It can also be used as PIO[5].
PIO4
(1)
PCS[4]#
H3
I/O [4mA]
OUT [4mA]
Peripheral Chip Select Output (Active LOW)
This pin indicates to the system that a bus cycle is in progress to
address 0x800 of the peripheral space.
It can also be used as PIO[4].
PIO3
(1)
PCS[5]#
K3
I/O [4mA]
OUT [4mA]
Peripheral Chip Select Output (Active LOW)
This pin indicates to the system that a bus cycle is in progress to
address 0xA00 of the peripheral space.
It can also be used as PIO[3].
PIO2
(1)
PCS[6]#
K2
I/O [4mA]
OUT [4mA]
Peripheral Chip Select Output (Active LOW)
This pin indicates to the system that a bus cycle is in progress to
address 0xC00 of the peripheral space.
It can also be used as PIO[2].
UCSIN#
U5
IN
Upper Memory Chip Select Input (Active LOW)
This pin should ALWAYS be connected to UCSOUT#, except when
an additional external memory (NV-SRAM, Flash) is used (e.g. see
chapter 11.3).
UCSOUT#
U6
OUT [4mA]
Upper Memory Chip Select Output (Active LOW)
This pin should always be connected to UCSIN#, except when an
additional external memory (NV-SRAM, Flash) is used (e.g. see
chapter 11.3).
FLSSEL
J3
OUT [4mA]
Flash Select
This pin is for selecting external memory. If this pin is high, the
internal flash is selected. When low, external memory can be
accessed
(E.g. see chapter 11.3).
