JTAG In-System Programming (ISP)
Port C is JTAG compliant, and can be used for In-
System Programming (ISP). You can multiplex
JTAG operations with other functions on Port C
because ISP is not performed during normal sys-
tem operation. For more information on the JTAG
Port, see the section entitled
PROGRAMMING IN-
CIRCUIT
USING
THE
INTERFACE, page 71
.
Port Configuration Registers (PCR)
Each Port has a set of Port Configuration Regis-
ters (PCR) used for configuration. The contents of
the registers can be accessed by the MCU through
normal READ/WRITE bus cycles at the addresses
given in
Table 6., page 17
. The addresses in
Ta-
ble 6., page 17
are the offsets in hexadecimal from
the base of the CSIOP register.
JTAG
SERIAL
The pins of a port are individually configurable and
each bit in the register controls its respective pin.
For example, Bit 0 in a register refers to Bit 0 of its
port. The three Port Configuration Registers
(PCR), shown in Table
22
, are used for setting the
Port configurations. The default Power-up state for
each register in Table
22
is 00h.
Control Register
Any bit reset to
‘
0
’
in the Control Register sets the
corresponding port pin to MCU I/O Mode, and a
‘
1
’
sets it to Address Out Mode. The default mode is
MCU I/O. Only Ports A and B have an associated
Control Register.
