Bus Control
Bus Control
Table 1.9.1. External areas specified by the chip select signals
Note :Be sure to set bit 3 (PM13) of processor mode register 1 to “0”.
(A product having an internal RAM equal to or less than 15K bytes and a ROM equal to or less than 192K bytes)(Note)
Memory expansion mode
Microprocessor mode
The following explains the signals required for accessing external devices and software waits. The signals
required for accessing the external devices are valid when the processor mode is set to memory expansion
mode and microprocessor mode. The software waits are valid in all processor modes.
(1) Address bus/data bus
(2) Chip select signal
The address bus consists of the 20 pins A
The data bus consists of the pins for data I/O. When the BYTE pin is “H”, the 8 ports D
as the data bus. When BYTE is “L”, the 16 ports D
When a change is made from single-chip mode to memory expansion mode, the value of the address
bus is undefined until external memory is accessed.
The chip select signal is output using the same pins as P4
register (address 0008
select control register is valid in memory expansion mode and microprocessor mode. In single-chip
mode, P4
register.
In microprocessor mode, only CS0 outputs the chip select signal after the reset state has been can-
celled. CS1 to CS3 function as input ports. Figure 1.9.1 shows the chip select control register.
The chip select signal can be used to split the external area into as many as four blocks. Tables 1.9.1
and 1.9.2 show the external memory areas specified using the chip select signal.
