AT89C5132 Errata History
AT89C5132 Errata Description
1. SPI Controller
2. C51 Core
Lot Number
A00960 and above
SPI Controller – Bad Transfer in Slave Mode with CPHA = 0
C51 Core – Bad Exit of Power-down in X2 Mode
SPI controller used in slave mode with CPHA = 0 leads to erratic data reception
and transmission.
Workaround
Use slave mode only with CPHA = 1.
When exiting Power-down mode by interrupt while CPU is in X2 mode, it leads to
bad execution of first instruction executed when CPU restarts.
Workaround
Put the CPU in X1 mode just before entering power-down mode.
Bad Exit of Power-down in X2 Mode
Bad Transfer in Slave Mode with CPHA = 0
