This register is used to enable test mode in the analog blocks. These bits are valid when
PMCATST is set to logic 1.
Access to this register is not affected by the Test Mode Address Force functions in registers
4001H and 4002H.
SYS_ATMSB
Global System side analog MABC test mode select. This signal is to be driven to logic ‘0’
whenever an individual ABC ATMSB is at logic ‘0’. SYS_ATMSB bits are cleared only
when CSB is logic 1 or when they are written to logic 0.
R8TD_SCLKE
When enabled, this register bit muxes the system clock on the R8TD piclk in order to apply
scan vectors. R8TD_SCLKE bits are cleared only when CSB is logic 1 or when they are
written to logic 0.
T8TE_SCLKE
When enabled, this register bit muxes the system clock on the T8TD poclk in order to apply
scan vectors. T8TE_SCLKE bits are cleared only when CSB is logic 1 or when they are
written to logic 0.
