Notes 1 : After the expansion function select bit (bit 5 of particular function select register 1) is “1”, bits 1, 5 and 6 can be rewritten.
4
2 : To set bits 1 to 4, continuous-twice-write operation must be performed to address 6C
3 : When the signal output disable select bit is “1” and bit 5 is “1”, the E pin always outputs “L” independent of bit 6’s contents

SHINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
Fix to “0”
Particular function select register 0
External clock input select bit (Notes 1, 2)
0 : Actuated oscillation circuit; connecting resonator
1 : Stopped oscillation circuit; inputting externally generated clock
Memory allocation select bits 2, 1, 0 (Note 2)
0 0 0 : ROM 120 Kbytes, RAM 3968 bytes
0 0 1 : ROM 92 Kbytes, RAM 3968 bytes
0 1 0 : ROM 60 Kbytes, RAM 3072 bytes
0 1 1 : ROM 56 Kbytes, RAM 3072 bytes
1 0 0 : ROM 48 Kbytes, RAM 2048 bytes
1 0 1 : ROM 32 Kbytes, RAM 2048 bytes
1 1 0 : ROM 60 Kbytes, RAM 2048 bytes
1 1 1 : ROM 56 Kbytes, RAM 2048 bytes
Standby state select bit 0 (Note 1)
; when WIT or STP instruction is executed in memory expansion
or microprocessor mode
0 : Pins P0 to P3 are for external data bus.
1 : Pins P0 to P3 are for port output or port input.
Standby state select bit 1 (Notes 1, 3)
; in execution of WIT or STP instruction
0 : “H” or “L” output for pin E
1 : “H” output for pin E
STP return select bit
0 : Watchdog timer is used when returning from Stop mode
1 : Watchdog timer is not used when returning from Stop mode; the microcomputer returns at once.
