REGISTER
Input data registers 1/2 (ODR1/2)
This is an 8-bit read/write enable register for the PCP
III
and 8-bit read-
only register for the host CPU.
The initial value is undefined when the system is reset or in the stand-by
mode.Register
Output data registers 1/2 (ODR1/2)
This is an 8-bit read/write enable register for the PCP
III
and 8-bit read-
only register for the host CPU.
The initial value is undefined when the system is reset or in the stand-by
mode.
STATUS REGISTER 1/2 (STR1/2)
This shows the status of host interface processing.
Error (ERR)
This indicates that the main routine of the PCP
III
is destroyed and the
loader of the boot block A or B waits for loading of write/erase control
program.
Command/data (C/D)
When the host CPU writes data to IDR, the status of HA0 is written and
whether the content of IDR is data or command is identified.
Ready/Busy (R/B)
This register indicates that the PCP
III
is performing internal processing
and cannot receive any command from the host.
The bit becomes 0 when:
• The PCP
III
is initialized after turned on
• The PCP
III
does not want to receive any command (data) from the
hostor any reason although the input data register full (IBF) is 0.
Input data register full (IBF)
When the host CPU writes data in the IDR, the IBF bit is set to 1. This
becomes a factor for internal interruption against the PCPIII.
When the PCP
III
reads data from the IDR, the IBF bit is cleared to 0.
Data read from the IDR is once stored in the host receive buffer com-
posed of the ring buffer.
posed of the ring buffer.
If the host receive buffer is full, IBF interruption should be inhibited and
any command from the host should not be received.
Output data register full (OBF)
When the PCP
III
writes ODR, the OBF bit is set to 1.
When the host CPU read ODR, the OBF bit is cleared to 0.
