5. Table of Special function registers (SFRs)
The SFRs include the I/O ports and peripheral control registers allocated to the 8-Kbyte address
space from 000000H to 001FF0H.
(1) I/O Port (13) Clock gear, PLL
(2) Interrupt control (14) 8-bit timer
(3) Memory controller (15) 16-bit timer
(4) TSI(Touch screen I/F) (16) SIO
(5) SDRAM controller (17) SBI
(6) LCD controller (18) AD converter

Remarks
Note: “Prohibit RMW” in the table means that you cannot use RMW instructions on these register.
Example: When setting bit0 only of the register PxCR, the instruction “SET 0, (PxCR)” cannot be
used. The LD (transfer) instruction must be used to write all eight bits.
Read/Write
R/W: Both read and write are possible.
R: Only read is possible.
W: Only write is possible.
W*: Both read and write are possible (when this bit is read as1)
Prohibit RMW: Read modify write instructions are prohibited. (The EX, ADD, ADC, BUS,
SBC, INC, DEC, AND, OR, XOR, STCF, RES, SET, CHG, TSET, RLC,
RRC, RL, RR, SLA, SRA, SLL, SRL, RLD and RRD instruction are read
modify write instructions.)
R/W*: Read modify write is prohibited when controlling the pull-up resistor.
