TSC80251G2D
UCONFIG1
Configuration Byte 1
Notes:
1. The CSIZE is only available on EPROM/OTPROM products.
2. Two or four bytes are transparently popped according to INTR when using the RETI instruction. INTR must be set if interrupts are used
with code executing outside region FF:.
3. Use only for Step A compatibility; set this bit when WSB1:0# are used.
Figure 8. Configuration Byte 1
Table 13. Address Ranges and Usage of RD#, WR# and PSEN# Signals
Note:
1. This selection provides compatibility with the standard 80C51 hardware which has separate external memory spaces for data and code.

Interrupt Mode bit
(2)
Clear so that the interrupts push two bytes onto the stack (the two lower bytes of the PC register).
Set so that the interrupts push four bytes onto the stack (the three bytes of the PC register and the
PSW1 register).
Wait State B bit
