2: TestResSys

3: TestPOR

For EM test only

p = defined by POR at ‘0’ (power on reset) only

P = defined by POR at ‘1’ (power on reset) only

x = undefined state by reset (register must be written before used)

RegTestEm1 and RegTestEm2 can be written only if ChTmDis in RegSysCntl1 is ‘0’. They are used for EM

test only and are Write only. To prevent entering test mode in normal operation one has to set the ChTmDis bit

to ‘1’ as soon as possible after reset. It should be one of first instructions.
